Transmit Timeslot and Transmit Highway Selection, Read/Write (08H/88H) (For MPI mode only)
The Transmit Timeslot selection bits (TT[6:0]) determine which time slot will be used to transmit the data of the corresponding channel.
The valid value of TT[6:0] is 0d - 127d, corresponding to TS0 to TS127. The default value is N for Channel N+1 (N = 0 to 7).
The Transmit Highway Selection bit (THS) selects a PCM highway for the corresponding channel to transmit the voice data.
THS = 0:
THS = 1:
Receive Timeslot and Highway Selection, Read/Write (09H/89H) (For MPI mode only)
The Receive Timeslot selection bits RT[6:0] determine which time slot will be used for the corresponding channel to receive the data. The
valid value of RT[6:0] is 0d - 127d, corresponding to TS0 to TS127. The default value is N for Channel N+1 (N = 0 to 7).
The Receive Highway Selection bit RHS selects a PCM highway for the corresponding channel to receive the voice data.
RHS = 0:
RHS = 1:
SLIC I/O Data, Read/Write (0AH/8AH) (For MPI mode only)
The SLIC I/O Data register contains the information of the SLIC I/O pins SI1, SI2, SB1, SB2, SO1, SO2 and SO3 on the corresponding
channel. The default value of this register is 0d. It should be noted that the SI1, SI2, SB1 and SB2 bits in this register are read only.
D/A Gain and A/D Gain Setting, Channel Power Down, Read/Write (0CH/8CH)
The GDA bit is used to set the analog gain of D/A for the corresponding channel.
GDA = 0:
GDA = 1:
The GAD bit is used to set the analog gain of A/D for the corresponding channel.
GAD = 0:
GAD = 1:
The Channel Power Down bit (PD) disables or enables the corresponding channel.
PD = 0:
PD = 1:
