Table 82. Line Input to Record Path Quick Setup Register
Table 81. Analog Microphone/Direct Input to Record Path Quick Setup Register
The analog microphone/direct input to record path quick
setup register (Table 81) is used to select and program
an analog input and to configure the digital record path.
The configuration bits in this register program the DAI I/O
configuration register (Table 45), the input enable register
(Table 7), and the appropriate input mixer, volume, and
control registers (analog microphone or direct to ADC
mixer).
The line input to record path quick setup register (Table 82)
is used to program the analog input and to configure the
digital record path. The configuration bits in this register
program the DAI I/O configuration register (Table 45), the
input enable register (Table 7), and the appropriate input
mixer, volume, and control registers (single-ended or dif-
ferential line input).
