Analog Module
14.7.3 Analog Module Status and Control Register (AMSCR)
Data Sheet

GAINB[3:0] — Analog Module 2nd-stage Gain Control Bits
GAINA[3:0] — Analog Module 1st-stage Gain Control Bits
The analog module status and control register (AMSCR):
These read/write bits define the 2nd-stage gain of the two-stage
amplifier. The overall gain of the amplifier equals the 1st-stage gain
multiplied by the 2nd-stage gain. Reset clears the GAINB[3:0] bits.
These read/write bits define the 1st-stage gain of the two-stage
amplifier. The overall gain of the amplifier equals the 1st-stage gain
multiplied by the 2nd-stage gain. Reset clears the GAINA[3:0] bits.
