Powerdown Line-Side Device.
0 = Normal operation. Program the clock generator before clearing this bit.
1 = Places the line-side device in lower power mode.
Powerdown System-Side Device.
0 = Normal operation.
1 = Powers down the system-side device. A pulse on RESET is required to restore normal
operation.
High-Speed Sampling Mode.
0 = Sample Rate is 8 kHz.
1 = Sample Rate is 16 kHz. The PCM or the GCI highway continues to be at 8 kHz; thus,
twice as many samples are generated per device timeslot. Samples are transmitted in adja-
cent timeslots.
Read returns zero.
Read returns zero.
