FUNCTION
APIN
LRCLK_A/GPIO Configuration:
00 = General-purpose input
01 = Word clock for the ADC
10 = General-purpose output—low
11 = General-purpose output—high
When APIN
≠ 01, LRCLK_D is used as the word clock for both the DAC and ADC. AWCI, ABCI, and
ADLY are still active and independent from the DAC mode bit settings when operating with a shared
LRCLK_D.
ADLY
ADC Data Delay
0—The most significant bit of an audio word is valid at the first BCLK edge after the LRCLK_A
transition.
1—The most significant bit of an audio word is valid at the second BCLK edge after the LRCLK_A
transition.
(ADLY = 1 for I2S-compatible mode)
APLLEN
ADC PLL Enable. This bit only applies when APIN = 01. When APIN
≠ 01 use DPLLEN for both the
DAC and ADC:
0 (Valid for slave and master mode)—The frequency of LRCLK_A is set by the ADCNI divider bits. In
master mode, the MAX9856 generates LRCLK_A using the specified divide ratio. In slave mode, the
MAX9856 expects an LRCLK_A using specified divide ratio.
1 (Valid for slave mode only)—A digital PLL locks on to any externally supplied LRCLK_A signal
regardless of the MCLK frequency.
ADCNI
ADC LRCLK Divider. If APIN
≠ 01, use DACNI for both the DAC and ADC. When APLLEN is set low,
the frequency of LRCLK_A is determined by ADCNI. See Table 6 for common ADCNI values:
ADCNI = (65536 x 96 x fLRCLK_A)/fPCLK.
fLRCLK_A = LRCLK_A frequency.
fPCLK = Prescaled MCLK internal clock frequency (PCLK).
ADC Output Gain. Specifies the gain applied to the digital output of the ADC prior to being output
from the device.
