Transmit Clock. 1.544 MHz primary clock.
Transmit Serial Data. Transmit NRZ serial data, sampled on the falling edge
of TCLK.
Transmit Channel Clock. 192 kHz clock which pulses high during the LSB
of each channel. Useful for parallel to serial conversion of channel data,
locating Robbed-Bit signaling bits, and for blocking clocks in DDS applica-
tions. See Section 13 for timing details.
Address/Data Bus. An 8-bit multiplexed address/data bus.
