QSPI Controller Peripheral Configuration

Map QSPI controller peripherals in the Infineon AURIX model to peripheral registers in the MCU

Since R2024a

Description

View and edit the map of peripherals in the Infineon^® AURIX™ model to the hardware peripherals.

Using the Peripheral Configuration tool, you can:

• View and edit configuration parameters for QSPI controller block.

• Configure the global parameters. To set the group peripheral, select peripheral in Browser > Peripherals > QSPI Controller . For more, see Map Tasks and Peripherals Using Hardware Mapping.

• Check for any conflicts between peripherals.

×

Open the QSPI Controller Peripheral Configuration

• In the Simulink toolstrip, go to Hardware tab and click Hardware Mapping.

  

Parameters

Global parameters > Module # > Events

Enable Tx FIFO event — Option to enable QSPI transmit buffer interrupt

off (default) | on

Enables the QSPI transmit FIFO interrupt.

When you select this option, the dialog box displays the Tx FIFO Mode Selection options.

Note

Enabling this parameter, expect that the data is handled through interrupts. Therefore it is mandatory to use QSPI Peripheral block (Transfer mode as SPI Transmit) or QSPI Controller (Transfer mode as SPI Transmit or SPI Transmit and Receive) block during the events.

Tx FIFO mode — FIFO flag mode setting for Tx FIFO buffer

Batch Move (default) | Single Move

This parameter is read-only.

Select one of these operation modes for Tx FIFO buffer:

• Single Move — Select this mode to generate an interrupt to refill the transmit buffer as soon as there is a free element.

• Batch Move — Select this mode to generate an interrupt if the FIFO level of Tx data exceeds above programmed threshold.

Dependencies

To enable this parameter, select the Enable Tx FIFO event parameter.

Tx FIFO threshold — FIFO level for Tx FIFO event

1 (default) | 2 | 3 | 4

Specify FIFO level for Tx FIFO event.

Dependencies

To enable this parameter, select the Enable Tx FIFO event parameter.

Enable Rx FIFO event — Option to enable receive buffer interrupt

off (default) | on

Enables the QSPI receive FIFO interrupt.

When you select this option, the dialog box displays the Rx FIFO Mode Selection options.

Note

Enabling this parameter, expect that the data is handled through interrupts. Therefore it is mandatory to use QSPI Peripheral block (Transfer mode as SPI Receive) or QSPI Controller block (Transfer mode as SPI Receive or SPI Transmit and Receive) during the events.

Rx FIFO mode — FIFO flag mode setting for receive buffer

Batch Move (default) | Single Move

This parameter is read-only.

Select one of these operation modes for receive buffer:

• Single Move — Select this mode to generate an interrupt to fetch the received element as soon as possible.

• Batch Move — Select this mode to generate an interrupt if the filling level rises above the programmed threshold.

Dependencies

To enable this parameter, select the RxFifo event parameter.

Rx FIFO threshold — FIFO level for Rx FIFO event

0 (default) | 1 | 2 | 3

Specify FIFO level for Rx FIFO event.

Dependencies

To enable this parameter, select the Enable Rx FIFO event parameter.

Enable error event — Option to enable error interrupt

off (default) | on

Enables the QSPI error interrupt.

Note

Enabling this parameter, expects that the data is handled through interrupts. Therefore it is recommended to use QSPI block (SPI receive or transmit as transfer mode) during the events.

Global parameters > Module # > Pin selection

Serial Clock pin (SCK) — Pin selection for serial clock

pin numbers

Select the QSPI serial clock pin selection. The available pin numbers vary based on the module selected.

Serial Data Out pin (SDO) — QSPI serial data out pin selection

pin numbers

Serial Data In pin (SDI) — QSPI serial data input pin selection

pin numbers

Select the QSPI serial data input pin selection. The available pin numbers vary based on the module selected.

Global parameters > Module # > Common pin properties

Input pins pull — Input pull for QSPI pin

Pull-down (default) | Tri-state | Pull-up

Select input pull for QSPI pin.

Select voltage level of QSPI pin.

Module

Module — Option to select the controller module

0 (default) | 1 | 2 | ...

Select the QSPI controller module 0 through 4 on the hardware board.

Tx mode

Tx mode — QSPI transmit mode

Continuous (default) | Single transfer

Select the QSPI transmit mode.

• Continuous - This option activates the chip select signal till the data transfer completes.

• Single-transfer - This option deactivates the chip select signal for every data element involved in the data transfer.

Clock

Baud rate — Configure baud rate for SPI transaction

1000000 (default) | positive scalar integer

Specifies the rate of data communication between the peripherals connected (clock period).

Data heading (Endianness) — QSPI data heading in binary

MSB first (default) | LSB first

Select the QSPI data heading in binary numbers.

• MSB first - the bit furthest to the left (msb) is moved first from SDO pin followed by the subsequent left bits.

• LSB first - the bit furthest to the right (lsb) is moved first from SDO pin followed by the subsequent right bits.

Polarity — Clock polarity in idle state

Idle low (default) | Idle High

Select the QSPI clock polarity in idle state.

Phase — QSPI clock phase

Trailing edge (default) | Leading edge

Select the QSPI clock phase.

Enable parity — Enable QSPI clock parity

off (default) | on

Enables the QSPI clock parity.

When you select the Enable parity parameter, the dialog box displays the Parity parameter.
