MAC0
Monitor Transmit Channel 0 Active (Read Only)
Data transmission is in progress in GCI mode Monitor channel 0.
0: the previous transmission has been terminated. Before starting a transmission, the microprocessor should verify
that the transmitter is inactive.
1: after having written data into the Monitor Transmit Channel 0 (MO0X) register, the microprocessor sets this bit to 1.
This enables the MX bit to go active (0), indicating the presence of valid Monitor channel data (contents of MOX) in
the correspond frame.
MAC1
Monitor Transmit Channel 1 Active (Read Only)
Data transmission is in progress in GCI mode Monitor channel 1.
0: the previous transmission has been terminated. Before starting a transmission, the microprocessor should verify
that the transmitter is inactive.
1: after having written data into the Monitor Transmit Channel
1 (MO1X) register, the microprocessor sets this bit to 1.
This enables the MX bit to go active (0), indicating the presence of valid Monitor channel data (contents of MOX) in
the correspond frame.
GACT
GCI Switching Active
Determines which CODEC interface is to be activated in B channle switching. Valid only in GCI master mode. In GCI slave
mode, PCM ports are always enabled.
0: PCM ports are enabled
1: GCI bus is enabled.
TLP
Test Loop
When this bit is set to 1 both the DU and DD lines are internally connected together. External input on DD is ignored. Valid
in GCI slave mode.
GRLP
GCI Mode Remote Loop-back
Setting this bit to 1 activates the remote loop-back function. The 2B+D channels data received from the GCI bus (DD)
interface are looped to the transmitted channels (DU). Valid in GCI slave mode.

Description

1
After U transceiver power down, W6692A will receive the
indication DC (Deactivation Confirmation)
from GCI bus and then software has to set SPU
→ 0, PD →1 to acknowledge U transceiver, by pulling DU
pin to HIGH. W6692A remains normal operation.
1
0
Setting SPU
→ 1, PD →0 will pull the GCI bus
DU line to low. This will enforce connected layer 1
devices (U transceiver) to deliver GCI bus clocking.
0
After reception of the indication PU (Power Up indication) the reaction of the microprocessor should be:
- To write an AR (Activate Request command) as C/I command code in the CIX register.
