PRODUCTION DATA.
Internal PWM channels 1, 2, 1, and 2 are mapped into registers 0x11, 0x12, 0x13, and 0x14.
BITS DEFINITION | D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 | FUNCTION | |
---|---|---|---|---|---|---|---|---|---|---|
0 | 0 | 0 | 0 | 0 | 0 | – | – | Minimum absolute delay, 0 DCLK cycles | ||
0 | 1 | 1 | 1 | 1 | 1 | – | – | Maximum positive delay, 31 × 4 DCLK cycles | ||
1 | 0 | 0 | 0 | 0 | 0 | – | – | Maximum negative delay, –32 × 4 DCLK cycles | ||
0 | 0 | Reserved | ||||||||
SUBADDRESS | D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 | Delay = (value) × 4 DCLKs | |
0x11 | 1 | 0 | 1 | 0 | 1 | 1 | – | – | Default value for channel 1(1) | |
0x12 | 0 | 1 | 0 | 1 | 0 | 1 | – | – | Default value for channel 2(1) | |
0x13 | 1 | 0 | 1 | 0 | 1 | 1 | – | – | Default value for channel 1(1) | |
0x14 | 0 | 1 | 0 | 1 | 0 | 1 | – | – | Default value for channel 2(1) |
ICD settings have high impact on audio performance (e.g., dynamic range, THD, crosstalk, etc.) Therefore, appropriate ICD settings must be used. By default, the device has ICD settings for the AD mode. If used in BD mode, then update these registers before coming out of all-channel shutdown.
MODE | AD MODE | BD MODE |
---|---|---|
0x11 | AC | B8 |
0x12 | 54 | 60 |
0x13 | AC | A0 |
0x14 | 54 | 48 |
