2.048 MHz. TXSYI has a rising edge prior to the sampling of the first bit of time
slot 0. This signal can be present every 2 ms. TXDATO is the output signal; it
transitions in response to the rising edge of TXCKI, and can be sampled on the
following falling edge. The content of time slot 0 and time slot 16 of the output is
undefined.
