9.16.1.5.4 IOM MODE
In the IOM format, the PCM_CLK frequency is twice the data bit cell duration. In slave
mode synchronization is on the first rising edge of PCM_FSC while data is clock in on
the second falling edge.
Settings for IOM mode:
• PCM_FSC_EDGE: 0 (rising edge PCM_FSC)
• PCM_FSCLEN: 0 (one cycle)
• PCM_FSC_DEL: 0 (no bit delay)
• PCM_CLK_INV: 0 (output on rising edge)
• PCM_CH0_DEL: 0 (no delay)
• PCM_CLK_BIT: 1
