set all bits of time-slot to low impedance
PCM-port 0, time-slot 5
write only single tri-state control position
Wait for STAR:MAC = 0
set SACCO-B to 8-bit non-auto mode; switch receiver active
the high-byte comparison registers should be set to 00
when using non-auto mode
8-bit address of SACCO-B
8-bit group address (broadcast by group controller)
TxDB pin enabled; standard data sampling; RFS-interrupt
disabled
power-up SACCO-B in point-to-point configuration and
