The DS26502 does not have an internal source for CAS signaling and multiframe alignment generation. CAS
signaling, and the multiframe alignment word, must be embedded in the transmit data (in the TS16 position) present
on the TSER pin and frame aligned to sync signal on the TS_8K_4 pin.
In addition to setting the TMODE bits to 6312kHz Synchronization Interface mode, the Transmit PLL must also be
configured to transmit a 6312kHz signal through the Transmit PLL Control Register (TPCR.6 and TPCR.7).
