GREG6: MCLK Selection and Channel Program Enable, Read/Write (25H/A5H)
The higher 4 bits (CE[3:0]) in this register are used to specify the desired channel(s) before addressing local registers or Coe-RAM. The
CE[0] to CE[3] bits indicate the program enable state for Channel 1 to Channel 4 respectively.
CE[0] = 0:
Disabled, Channel 1 can not receive programming commands (default);
CE[0] = 1:
Enabled, Channel 1 can receive programming commands;
CE[1] = 0:
Disabled, Channel 2 can not receive programming commands (default);
CE[1] = 1:
Enabled, Channel 2 can receive programming commands;
CE[2] = 0:
Disabled, Channel 3 can not receive programming commands (default);
CE[2] = 1:
Enabled, Channel 3 can receive programming commands;
CE[3] = 0:
Disabled, Channel 4 can not receive programming commands (default);
CE[3] = 1:
Enabled, Channel 4 can receive programming commands.
The lower 4 bits (Sel[3:0]) in this register are used to select the Master Clock frequency.
Sel[3:0] = 0000:
8.192 MHz
Sel[3:0] = 0001:
4.096 MHz
Sel[3:0] = 0010:
2.048 MHz (default)
Sel[3:0] = 0110:
1.536 MHz
Sel[3:0] = 1110:
1.544 MHz
Sel[3:0] = 0101:
3.072 MHz
Sel[3:0] = 1101:
3.088 MHz
Sel[3:0] = 0100:
6.144 MHz
Sel[3:0] = 1100:
6.176 MHz
GREG7: A/
μ
-law, Linear/Compressed Code, Clock Slope and Delay Time Selection, Read/Write (26H/A6H)
The A/
μ
-law select bit (A-
μ
) selects the companding law:
A-
μ
= 0:
A-law is selected (default)
A-
μ
= 1:
μ
-law is selected.
The Voice Data Select bit (VDS) defines the format of the voice data:
VDS = 0:
Compressed code (default)
VDS = 1:
Linear code
The Clock Slope bits (CS[2:0]) select single or double clock and clock edges of transmitting and receiving data.
CS[2] = 0:
Single clock (default)
CS[2] = 1:
Double clock
CS[1:0] = 00:
CS[1:0] = 01:
transmits data on rising edges of BCLK, receives data on falling edges of BCLK (default).
transmits data on rising edges of BCLK, receives data on rising edges of BCLK.
