21.4
21.4.1
The SPI flash memory transfer is performed using FSIDO and FSIDI synchronously with FSICK.
The initial value of FSICK can be either fixed to high or low through programming.
21.4.2
The FSI has two communications functions to perform data transfer with the flash memory:
transmit and receive operations. Up to seven bytes of addresses or data items are transmitted in
each transmit operation. Up to four bytes of data items are received in each receive operation, and
the received data is stored in on-chip FIFOs. Issue FSI transmit and receive operations following
the setting procedures shown in figure 21.3.
