DESCRIPTION

R35 (23h)

DAC IN1

3:2

INTM[1:0]

When LINEBYLINE=1,

controls the GAIN and DAC mux selector when ACYC=0

00 = IN7

01 = IN8

10 = IN9

11 = reserved

ACYC

when LINEBYLINE=1, determines the function of the MUX control

0 = decided by INTM register

1= auto-cycling enabled

LINEBYLINE

select line by line operation

0=normal operation

1=Line by Line operation
