MSK128: Mask for fS = 128 kHz
0: No mask (default)
1: Mask
PCM9211 does not receive 128-kHz sampling frequency.
This register setting is effective with NOMLMT = '1'.
MSK64: Mask for fS = 64 kHz
0: No mask (default)
1: Mask
PCM9211 does not receive 64-kHz sampling frequency.
This register setting is effective with NOMLMT = '1'.
NOMLMT: Receive Nominal Audio fS within ±2%
0: No limit (default)
1: Limit
PCM9211 receives the nominal audio sampling frequencies within ±2%.
The nominal audio sampling frequencies are: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz,
32 kHz, 44.1 kHz, 48 kHz, 64 kHz, 88.2 kHz, 96 kHz, 128 kHz, 176.4 kHz, 192 kHz
HILMT[1:0]: Acceptable fS Higher Limit Setting
00: No limit (default)
01: fS = 54 kHz
10: fS = 108 kHz
11: fS = 216 kHz
LOLMT[1:0]: Acceptable fS Lower Limit Setting
00: No limit (default)
01: fS = 7 kHz
10: fS = 14 kHz
11: fS = 28 kHz
This condition of receivable sampling frequency is used as the ERROR and AUTO source selection when
EFSLMT or AFSLMT is set to '1'.
