IDT821054 QUAD PROGRAMMABLE PCM CODEC WITH MPI INTERFACE
INDUSTRIAL TEMPERATURE RANGE
LREG4: Channel I/O Data, Read/Write (03H/83H)
The Channel I/O Data bits contain the information of the SLIC I/O pins (SI1, SI2, SB1, SB2, SB3, SO1 and SO2) of the corresponding
channel.
If SB1, SB2 and SB3 are configured as outputs, data can only be written to them by global registers GREG10, GREG11 and GREG12
respectively, and not by this register.
LREG5: Transmit Timeslot and Transmit Highway Selection, Read/Write (04H/84H)
The Transmit Time Slot Bits TT[6:0] select a time slot (compressed code) or a time slot group (linear code) for the corresponding channel
to transmit the PCM data. The valid value is from 0 to 127(d), corresponding to TS0 to TS127. The default value is 0 (d).
The Transmit Highway Selection bit THS selects a PCM highway for the corresponding channel to transmit the PCM data.
THS = 0:
DX1 is selected (default);
THS = 1:
DX2 is selected.
LREG6: Receive Timeslot and Receive PCM Highway Selection, Read/Write (05H/85H)
The Receive Time Slot Bits RT[6:0] select a time slot (compressed code) or a time slot group (linear code) for the corresponding channel
to receive the PCM data. The valid value is from 0 to 127(d), corresponding to TS0 to TS127. The default value is 0 (d).
The Receive Highway Selection bit RHS selects a PCM highway for the corresponding channel to receive the PCM data.
RHS = 0:
DR1 is selected (default);
RHS = 1:
DR2 is selected.
LREG7: PCM Data Low Byte, Read Only (06H)
This register is used for MCU to monitor the transmit (A to D) PCM data. For linear code, this register contains the low byte of the
transmit PCM data and LREG8 contains the high byte of the transmit PCM data. For compressed code (A/-Law), this register contains
total 8 bits of the transmit PCM data.
The low byte or total 8 bits of transmit PCM data will be read out by applying a read command to this register, and at the same time, it will
be transmitted to the PCM highway without any interference.
LREG8: PCM Data High Byte, Read Only (07H)
This register is used for MCU to monitor the transmit (A to D) PCM data. For linear code, this register contains the high byte of the
