Function
5—7
Receive direction bit offset for the FS signal. Defaults to 0. These 3 bits can be
thought of as the least significant bits (RXOFF contains the more significant bits)
of a bit counter that determines the location of the first bit of the PCM data from
FS.
Load as 0.
Receive time-slot assignment. Defaults to (16 * channel number). Each time slot
represents 8 bits, allow for two time slots when using linear mode.
Gain adjustment for gain transfer stage in receive direction. Defaults to 0x0400
(0 dB). This is an 11-bit multiply operation with a maximum gain of 2 (6 dB). 0 dB
is the maximum recommended setting.
Gain adjustment for tweak gain stage in receive direction. Defaults to 0x01ac
(
7.58 dB). This is an 11-bit multiply operation with a maximum gain of 2 (6 dB).
0 dB is the maximum recommended setting.
Load as 0s.
Peak detector tweaking control. Use default of 4.
