A2
A.1 Main Control Register (MCR)
Configuration of the digital serial audio interface is set up through the main control register as shown in Table A2
and Table A3. Bits F0 and F1 allow selection between three different serial data formats (left justified = 00, right
justified = 01, and I
2
S standard = 10). The output serial port mode set by E0 and E1 must be set to the same value
as the input serial port mode set by F0 and F1. Bits W0 and W1 allow selection between three different word widths
(16-bit word = 00, 18-bit word = 01, and 20-bit word = 10). The SC bit selects 32f
s
(0) or 64f
s
(1) bit clock. The FL
bit is primarily for use during initialization and is defined in
Device Initialization
(see Section 5.1). See Section 3,
Serial
Control Interface
, for additional information on how to address the main control register.
