Configurator-generated features limitations

List of SPI personality items, which are currently not supported in SPI HAL driver on CAT1/CAT2 devices:

• Modes: TI (Start Coincides), TI (Start Precedes), National Semiconductor (Microwire)
• Low-level RX Interrupt sources
• Low-level TX Interrupt sources
• SPI Done Master interrupt source
• Different data width for RX and TX

Supported transfer data width options

Next transfer data width options are supported by next devices:

• CAT1 devices with MXSCB block version 2 and further (value of CY_IP_MXSCB_VERSION) support next data width range: 4 - 32 (included) with step 1
• CAT1 devices with MXSCB block version 1 (value of CY_IP_MXSCB_VERSION) support next data width range: 4 - 16 (included) with step 1
• CAT2 devices support next data width range : 4-16 (included) with step 1
• CAT5 devices support data widths: 4,8,16,32

SPI master SS pin configured in GPIO mode

SPI master Slave Select pins are configured in GPIO mode to support asymmetric data transfers. Therefore these pins are not restricted to direct connections to the SPI hardware
