word on the first rising edge of the clock after F1i
and CA are taken low. The 8 bit TEM word from
the input ST-BUS stream is clocked into the device
on the negative edge of the C2i clock. For proper
codec operation, the ST-BUS interface (DSTo, DSTi,
and CSTi) should be enabled for only 8 clock periods
of the C2i clock in any 125μs period (one ST-BUS
frame time) as shown in Figure 11. All data input
and output at the ST-BUS interface takes place at
2.048 Mbps.
