ADCAnAMPCNT - A/D Converter Buffer Amplifier Count Register
This register specifies the operation time of the buffer amplifier. Set this
register, when the buffer amplifier function is enabled. If it is disabled, setting
this register is ignored.
Access
This register can be read/written in 8-bit units.
It can only be written when the A/D converter is disabled
(ADCAnCTL0.ADCAnCE = 0).
Address
<ADCAn_base0> + 134
H
Initial value
0C
H
This register is initialized by any reset.

ADCAnDISCNT - A/D Converter Discharge Count Register
This register specifies the discharge time. Set this register, when the discharge
function is enabled. If it is disabled, setting this register is ignored.
Access
This register can be read/written in 8-bit units.
It can only be written when the A/D converter is disabled
(ADCAnCTL0.ADCAnCE = 0).
Address
<ADCAn_base0> + 138
H
Initial value
0F
