Description

SPI0 external RAM bit mode control register.

Fields

CACHE_REQ_EN

Set this bit to enable Cache’s access and SPI0’s transfer.
CACHE_USR_CMD_4BYTE

Set this bit to enable SPI0 read flash with 32 bits address. The value of SPI_MEM_USR_ADDR_BITLEN should be 31.
CACHE_FLASH_USR_CMD

1: The command value of SPI0 reads flash is SPI_MEM_USR_COMMAND_VALUE. 0: Hardware read command value, controlled by SPI_MEM_FREAD_QIO, SPI_MEM_FREAD_DIO, SPI_MEM_FREAD_QUAD, SPI_MEM_FREAD_DUAL and SPI_MEM_FASTRD_MODE bits.
FDIN_DUAL

When SPI0 accesses to flash, set this bit to enable 2-bm in DIN phase.
FDOUT_DUAL

When SPI0 accesses to flash, set this bit to enable 2-bm in DOUT phase.
FADDR_DUAL

When SPI0 accesses to flash, set this bit to enable 2-bm in ADDR phase.
FDIN_QUAD

When SPI0 accesses to flash, set this bit to enable 4-bm in DIN phase.
FDOUT_QUAD

When SPI0 accesses to flash, set this bit to enable 4-bm in DOUT phase.
FADDR_QUAD

When SPI0 accesses to flash, set this bit to enable 4-bm in ADDR phase.
