The common transmit and receive clock is supplied at pin RxCLK and the common frame
synchronisation signal at pin FSC. The "strobe signals" for active time slots are
generated internally by the time slot assigner block (TSA) independent in transmit and
receive direction.
When the transmit and receive PCM masks are enabled, bit fields ’TCC’ and ’RCC’ are
ignored because of the constant 8-bit time slot width.
