Section 29 Serial I/O with FIFO (SIOF)
(1)
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 using the
REDG bit in SIMDR.
• Falling-edge sampling
• Rising-edge sampling
Figure 29.4 shows the transmit/receive timing.
29.4.3
The SIOF performs the following transfer.
• Transmit/receive data: Transfer of 8-bit data/16-bit data/16-bit stereo data
• Control data: Transfer of 16-bit data (uses the specific register as interface)
(1)
The SIOF supports the following four transfer modes as listed in table 29.6. The transfer mode can
be specified by the bits TRMD[1:0] in SIMDR.
