DESCRIPTION
SYMBOL VALUE
FUNCTION
D7 analog output select
AOSL2
see Table 60
D6 AD port output enable
ADPE
0
AD port is set to 3-state
1
AD port is enabled
D5 ADC clock selector
EXCLK
0
all ADCs are clocked by the internal generated line-locked
clock
1
all ADCs are clocked by the external input clock on CLKEXT
D4 clamping/reference
selection for all ADCs
REFA
0
clamping is dependent on HLNRS[03H[6]]
1
reference selection (input signal is pulled into ADC range)
D2 enable external source
switch indicator input
EXMCLR
EXMCE
0
disabled
1
enabled (any slope on EXMCLR input will reset the internal
gain control loop)
D1 static gain control channel 2
sign bit
GAI48
see Table 70
D0 static gain control channel 1
sign bit
