SYNC_SUPPRESS_EN 8
0 = enable PCM_SYNC output when master.
1 = suppress PCM_SYNC while keeping PCM_CLK
running. Some CODECS use this to enter a low
power state.
GCI_MODE_EN 9 1 = enable GCI mode.
MUTE_EN 10 1 = force BT_PCM_TXD_P to 0.
48M_PCM_CLK_GEN_EN 11
0 = set PCM_CLK and PCM_SYNC generation via
DDS from internal 4MHz clock.
1 = set PCM_CLK and PCM_SYNC generation via
DDS from internal 48MHz clock.
LONG_LENGTH_SYNC_EN 12
0 = set PCM_SYNC length to 8 PCM_CLK cycles.
1 = set length to 16 PCM_CLK cycles. Only applies
for long frame sync and with
48M_PCM_CLK_GEN_EN set to 1.
PCM_SYNC_MULT 13
0 = Sync limit = SYNC_LIMIT x 8.
1 = SYNC_LIMIT.
[20:16] Set to 0b00000
MASTER_CLK_RATE [22:21]
Selects 128 (0b01), 256 (0b00), 512 (0b10) kHz
BT_PCM_CLK+P frequency when master and
48M_PCM_CLK_GEN_EN (bit 11) is low.
ACTIVE_SLOT [26:23] Default is 0001. Ignored by firmware.
SAMPLE_FORMAT [28:27]
Selects between 13 (0b00), 16 (0b01), 8 (0b10) bit
sample with 16-cycle slot duration or 8 (0b11) bit
sample with 8-cycle slot duration.
