IDT821054 QUAD PROGRAMMABLE PCM CODEC WITH MPI INTERFACE INDUSTRIAL TEMPERATURE RANGE
transmit PCM data. For compressed code (A/μ-Law), this register is not used (when being read, it will output a data byte of 00H).
The high byte 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.
LREG9: A/D Gain, D/A Gain, Channel Power Down and PCM Receive Path Cutoff, Read/Write (08H/88H)
The Channel Power Down bit (PD) selects the operation mode for the corresponding channel:
PD = 0:
The corresponding channel is in normal operation state;
PD = 1:
The corresponding channel is powered down (default).
The PCMCT bit determines the operation of PCM Receive Path of the corresponding channel:
PCMCT = 0:
The PCM Receive Path of the corresponding channel is in normal operation state (default);
PCMCT = 1:
The PCM Receive Path of the corresponding channel is cut off.
The A/D Gain bit (GAD) sets the gain of analog A/D for the corresponding channel:
GAD = 0:
0 dB (default);
GAD = 1:
+6 dB.
The D/A Gain bit (GDA) sets the gain of analog D/A for the corresponding channel:
GDA = 0:
0 dB (default);
GDA = 1:
-6 dB.
Attention: To ensure proper operation, the lower 4 bits of the I/O data byte following the write command (88H) must be '0000'.
LREG10: Tone Generator Enable, Read/Write (09H/89H)
TEN1 = 0:
TEN1 = 1:
Tone generator 1 is disabled (default);
Tone generator 1 is enabled.
TEN0 = 0:
TEN0 = 1:
Tone generator 0 is disabled (default);
Tone generator 0 is enabled.
Attention: To ensure proper operation, the b3 and b2 of the I/O data byte following the write command (89H) must be ‘11’.
