7. PCM Data Offset, PCM Clock Slope, Data Mode Select, and A/
m
-Law Select (26H/A6H), Read/Write
PCM Data Offset bits (DO[2:0]) configure the number of clocks that PCM data transmit and receive time slot is offset from the Frame Synchro-
nous Signal (FS). (For MPI mode only)
DO[2:0] = 000: 0 BCLK period (default);
DO[2:0] = 001: 1 BCLK period;
DO[2:0] = 010: 2 BCLK periods;
DO[2:0] = 011: 3 BCLK periods;
DO[2:0] = 100: 4 BCLK periods;
DO[2:0] = 101: 5 BCLK periods;
DO[2:0] = 110: 6 BCLK periods;
DO[2:0] = 111: 7 BCLK periods.
PCM Clock Slope (CS[2:0]) bits select transmit and receive clock edge. (For MPI mode only)
CS[2] = 0: single clock (default);
CS[2] = 1: double clock;
CS[1:0] = 00: IDT821068 transmits data on rising edges of BCLK, and receives data on falling edges of BCLK (default);
CS[1:0] = 01: IDT821068 transmits data on rising edges of BCLK, and receives data on rising edges of BCLK;
CS[1:0] = 10: IDT821068 transmits data on falling edges of BCLK, and receives data on falling edges of BCLK;
CS[1:0] = 11: IDT821068 transmits data on falling edges of BCLK, and receives data on rising edges of BCLK.
Data Mode Select bit (DMS) defines the coding format of the voice data. (For both MPI and GCI mode)
DMS = 0: compressed code (default);
DMS = 1: linear code.
A/
μ
-law Select bit (LS) selects A-law or
μ
-law. (For both MPI and GCI mode)
LS = 0: A-law (default);
LS = 1:
μ
-law.
8. Chopper Clock Select (27H/A7H), Read/Write
CHCLK1_SEL bits configure the programmable output pin CHCLK1.
CHCLK1_SEL[3:0] = 0000: CHCLK1 outputs 1 permanently (default);
CHCLK1_SEL[3:0] = 0001: CHCLK1 outputs digital signal at the frequency of 1000/2 Hz;
CHCLK1_SEL[3:0] = 0010: CHCLK1 outputs digital signal at the frequency of 1000/4 Hz;
CHCLK1_SEL[3:0] = 0011: CHCLK1 outputs digital signal at the frequency of 1000/6 Hz;
CHCLK1_SEL[3:0] = 0100: CHCLK1 outputs digital signal at the frequency of 1000/8 Hz;
