6. MCLK Selection

(10h/12h)

MCLK may be selected to operate from a 2.048 MHz or 4.096 MHz external clock. MCLK

selection on either channel affects both channels.

A = 0:

2.048 MHz

A = 1:

4.096 MHz

7. Write Transmit Time Slot and PCM Highway Selection

(40h)

PCM = 0:

Highway A

PCM = 1:

Highway B

TS:

Time slot number 0 to 127

The PCM Highway B is not available on the Am79C031(A). The Transmit section of both

channels must not be set to the same time slot on the same output port simultaneously.

8. Read Transmit Time Slot and PCM Highway Selection

(41h)

9. Write Receive Time Slot and PCM Highway Selection

(42h)

PCM = 0:

Highway A

PCM = 1:

Highway B

TS:

Time slot number 0 to 127

The PCM Highway B is not available on the Am79C031(A).
