Operation
Control the write operation to the SPI
flash memory by the EC CPU. No wait
cycle is inserted to the LPC bus. Confirm
by FSIWBUSY whether or not a write
transfer has been completed.
Control the write operation to the SPI
flash memory by the EC CPU. Wait
cycles are inserted to the LPC bus.
Provision of wait cycles can be canceled
by clearing FSIWBUSY.
Control the write operation to the SPI
flash memory by the FSI. No wait cycle is
inserted to the LPC bus. Confirm by
LFBUSY whether or not a write transfer
has been completed.
Control the write operation to the SPI
flash memory by the FSI. Wait cycles are
inserted to the LPC bus. Provision of wait
cycles can be canceled by clearing
LFBUSY.
