CSTART
ADDx
Bits
15-12
Conversion start address. These bits select which ADC12
conversion-memory register is used for a single conversion or for the first
conversion in a sequence. The value of CSTARTADDx is 0 to 0Fh,
corresponding to ADC12MEM0 to ADC12MEM15.
SHSx

11 Timer_B.OUT1
SHP
Bit 9 Sample-and-hold pulse-mode select. This bit selects the source of the
sampling signal (SAMPCON) to be either the output of the sampling timer or
the sample-input signal directly.
0 SAMPCON signal is sourced from the sample-input signal.
1 SAMPCON signal is sourced from the sampling timer.
ISSH
Bit 8 Invert signal sample-and-hold
0 The sample-input signal is not inverted.
1 The sample-input signal is inverted.
