Section 20 Serial IO (SIOF)
(2) Transmit or Receive Timing
Timing to SCK_SIO for transmitting TXD_SIO or receiving RXD_SIO can be chosen from the
following two cases. Timing for transmitting or receiving is set into REDG bit in SIMDR register.
In slave mode 1 or slave mode 2, only the sample at falling is valid.
• Sample at falling
• Sample at rising
Figure 20.4 shows the timing for transmitting or receiving.
20.3.3
SIOF transmit two kind of data shown below.
• Transmit or receive data: Transmit data of 8 bit/16 bit/16 bit stereo
• Control data: 16 bit length (interface by using the dedicated register)
(1) Transmit Mode
SIOF has four modes as transmit mode shown in table 20.4. Transmit mode is set to bits TRMD1
to TRMD0 in SIMDR register.
