30 HMUTE_SET 5V Logic Input
Determines the state of HMUTE (pin 15) during a fault condition. If
HMUTE_SET is cleared to 0, the HMUTE will be low during a fault
condition. If HMUTE_SET is set to 1, then HMUTE will be high during a
fault condition.
31
OVRLDB
5V Logic Output
Indicates that one or more channels are near saturation
32
TST_EN
5V Logic Output
Digital output to put power stage in to test mode. Can be used as a
general purpose I/O during normal operation.
33
BYP_CAL
5V Logic Input If BYP_CAL is set to 1, the automatic DC calibration function is disabled.
If BYP_CAL is set to 0, the DC calibration function is performed at startup.
34
VA50
Power
5V analog power supply
35
GA50
Ground
Analog ground for VA50
36
AM_IN
5V Logic Input
If AM_IN is set to 1, the system uses AM mode.
37
SE/BRGB
5V Logic Input
Sets DCB control bit power up defaults and selects VCLAMP_SE or
VCLAMP_BR
38, GAIN0, GAIN1 5V Logic Input
Digital inputs which set the power up default modulator gain. GAIN0,
39
GAIN1=0 set the lowest gain, while GAIN0,GAIN1=1 set the highest gain
which is used for maximum output power for bridged applications.
