Description

SPI USER control register 1

Fields

SPI_USR_DUMMY_CYCLELEN

The length in spi_clk cycles of dummy phase. The register value shall be (cycle_num-1). Can be configured in CONF state.
SPI_MST_WFULL_ERR_END_EN

1: SPI transfer is ended when SPI RX AFIFO wfull error is valid in GP-SPI master FD/HD-mode. 0: SPI transfer is not ended when SPI RX AFIFO wfull error is valid in GP-SPI master FD/HD-mode.
SPI_CS_SETUP_TIME

(cycles+1) of prepare phase by spi clock this bits are combined with spi_cs_setup bit. Can be configured in CONF state.
SPI_CS_HOLD_TIME

delay cycles of cs pin by spi clock this bits are combined with spi_cs_hold bit. Can be configured in CONF state.
SPI_USR_ADDR_BITLEN

The length in bits of address phase. The register value shall be (bit_num-1). Can be configured in CONF state.
