It has 3 USI blocks which can be configured in SPI mode: * spi_0: BLK_PERI_SPI_0 (0x13940000) * spi_1: BLK_ALIVE_USI_CMGP00 (0x11d00000) * spi_2: BLK_ALIVE_USI_CMGP01 (0x11d20000) SPI FIFO depth is 64 bytes for all those SPI blocks, so the .fifo_lvl_mask value is set to 0x7f. All blocks have DIV_4 as the default internal clock divider, and an internal loopback mode to run a loopback test.
