8 CONTROL PORT REGISTER BIT DEFINITIONS
8.1
TRUNC – Determines if the audio word length is set according to the incoming channel status data as decoded by
the AUX[3:0] bits. The resulting word length in bits is 24-AUX[3:0].
Reserved
8.2
SWCLK - Lets OMCK determine RMCK, OSCLK, OLRCK when PLL loses lock
RMCKF – Recovered Master Clock Frequency
MUTESAO - Mute control for the serial audio output port
HOLD[1:0] – Determine how received audio sample is affected when a receive error occurs

[1:0] – These bits may change state depending on the input audio data.
Default = 0
0 – incoming data is not truncated
1 – incoming data is truncated according to the length specified in the channel status data
Truncation occurs before the de-emphasis filter. TRUNC has no effect on output data if de-emphasis
filter is not used.
Default = ‘0’
0 – Output clocks determined by PLL
1 – Output clocks determined by OMCK
Default = “0”
0 – Frequency is 256 FS
1 – Frequency is 128 FS
Default = ‘0’
0 - SDOUT (Not Muted)
1 – SDOUT (Muted)
Default = “00”
00 – hold last audio sample
01 – replace the current audio sample with 00 (mute)
10- do not change the received audio sample
