8.1.2 Long Frame Sync
Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data
words or samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the
PCM word. When WT21 is configured as PCM master, generating PCM_SYNC and PCM_CLK, then
PCM_SYNC is 8-bits long. When WT21 is configured as PCM Slave, PCM_SYNC may be from two
consecutive falling edges of PCM_CLK to half the PCM_SYNC rate, i.e., 62.5μs long.
