Function:
The required relationship between LRCK, SCLK and SDIN for the transmitter is defined by the Transmitter
Digital Interface Format and the options are detailed in
Function:
When this bit is cleared, the transmitter output pin driver will be in the normal operational mode. When
set, the transmitter output pin driver will drive to a constant 0 V.
Function:
When this bit is cleared, the transmitter data will be in the normal operational mode. When set, the trans-
mitter will output all zero data.
Function:
This bit sets the transmitted Validity bit level.
When this bit is cleared, valid linear PCM audio data is indicated. When this bit is set, invalid or non-linear
PCM audio data is indicated.
Function:
When this bit is cleared, the transmitter will operate in stereo mode. When set, the transmitter will operate
in Mono Mode with one input channel’s data output in both A and B subframes (see
Status (C) Bit Management” on page
Function:
When this bit is cleared, the transmitter will transmit the channel A CS data in the A subframe and the
channel B CS data in the B subframe.
When this bit is set, the transmitter will transmit the CS data defined for the channel selected by the
MMTLR bit in both the A and B subframes.
