Section 16 Serial I/O with FIFO (SIOF)
Frame Length: The length of the frame to be transferred by the SIOF is specified by the FL3 to
FL0 bits in SIMDR. Table 16.5 shows the relationship between the FL3 to FL0 bit settings and
frame length.

Slot Position: The SIOF can specify the position of transmit data, receive data, and control data in
a frame (common to transmission and reception) by slot numbers. The slot number of each data is
specified by the following registers.
• Transmit data: SITDAR
• Receive data: SIRDAR
• Control data: SICDAR
Only 16-bit data is valid for control data. In addition, control data is always assigned to the same
slot number both in transmission and reception.
