SPIDRV_Init Struct Reference

Detailed Description

SPI driver instance initialization structure. This data structure contains a number of SPIDRV configuration options. This struct is passed to SPIDRV_Init() when initializing a SPIDRV instance. Some common initialization data sets are predefined in SPIDRV_MASTER_USART0 and friends.
