Description

SPI1 wait idle control register

Fields

SPI_MEM_WAITI_EN

1: The hardware will wait idle after SE/PP/WRSR automatically, and hardware auto Suspend/Resume can be enabled. 0: The functions of hardware wait idle and auto Suspend/Resume are not supported.
SPI_MEM_WAITI_DUMMY

The dummy phase enable when wait flash idle (RDSR)
SPI_MEM_WAITI_ADDR_EN

1: Output address 0 in RDSR or read SUS command transfer. 0: Do not send out address in RDSR or read SUS command transfer.
SPI_MEM_WAITI_ADDR_CYCLELEN

When SPI_MEM_WAITI_ADDR_EN is set, the cycle length of sent out address is (SPI_MEM_WAITI_ADDR_CYCLELEN[1:0] + 1) SPI bus clock cycles. It is not active when SPI_MEM_WAITI_ADDR_EN is cleared.
SPI_MEM_WAITI_CMD_2B

1:The wait idle command bit length is 16. 0: The wait idle command bit length is 8.
SPI_MEM_WAITI_DUMMY_CYCLELEN

The dummy cycle length when wait flash idle(RDSR).
SPI_MEM_WAITI_CMD

The command value to wait flash idle(RDSR).
