R/W in I
0 - Disabled
Enabling this function will initiate a calibration to minimize the differential DC offset. This function will be
automatically reset following completion of the calibration sequence.
R/W in I
0 - Enabled
The analog outputs will ramp to a muted state when enabled. The ramp requires 1152 left/right clock cy-
cles in Single Speed, 2304 cycles in Double Speed and 4608 cycles in Quad Speed mode. The bias volt-
age on the outputs will be retained and MUTEC will go low at the completion of the ramp period.
The analog outputs will ramp to a normal state when this function transitions from the enabled to disabled
state. The ramp requires 1152 left/right clock cycles in Single Speed, 2304 cycles in Double Speed and
4608 cycles in Quad Speed mode. The MUTEC will go high immediately on disabling of MUTE.
