A-D control register 2 (Note)
b7 b6 b5 b4 b3 b2 b1 b0
000
Symbol
ADCON2
Address
03D416
When reset
0000XXX02
Bit symbol
Bit name
SMP
A-D conversion method
select bit
Reserved bit
Function
0 : Without sample and hold
1 : With sample and hold
Always set to “0”
RW
Nothing is assigned. Write "0" when writing to these bits.
When read, the value is "0".
SSH
Simultaneous sample and 0 : Disabled
hold
1 : Enabled
Note 1: If the A-D control register is rewritten during A-D conversion, the conversion
result is indeterminate.
Note 2: SSH must be used ony in conjunction with SMP.
Note 3: User must guarantee a conversion of input "1" after a conversion of input "0"
in all modes except sweep modes.
