Section 21 FSI Interface
21.3.6
FSITDR stores a total of eight bytes of transmit data. A total of 8 bytes of addresses, instructions,
and data items can be transferred continuously from FSITDR0 to FSITDR7 in this order to the SPI
flash memory, according to the setting of the TBN bits in FSIBNR. No data should be set to
FSITDR0 because the value of FSIINS is automatically stored in FSITDR0 when the
communications operation is started. The settings of this register should not be modified while the
FSI is performing communications.
21.3.7
FSIRDR stores a total of four bytes of receive data items continuously sent from the SPI flash
memory. This register should not be read unless the FSI has finished receiving data. Note that four
bytes of the receive register share a single register address. Which receive register is to be read
will be determined by the value of the RBN bits in FSIBNR. When RBN = B'000, H'00 is read
out.
