22. Serial I/O with FIFO (SIOF)
(2)
The SIOF_TXD transmit timing and SIOF_RXD receive timing relative to the SIOF_SCK can be
set as the sampling timing in the following two ways. The transmit/receive timing is set by the
REDG bit in SIMDR.
• Falling-edge sampling
• Rising-edge sampling
Figure 22.4 shows the transmit/receive timing.
