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
Function
0 : Without sample and hold
1 : With sample and hold
RW
Reserved bit
Must always be set to “0”
Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to
be “0”.
Note: If the A-D control register is rewritten during A-D conversion, the conversion
result is indeterminate.

(b8)
b0 b7
Symbol
ADi(i=0 to 7)
Address
When reset
03C016 to 03CF16 Indeterminate
b0
Function
Eight low-order bits of A-D conversion result
• During 10-bit mode
Two high-order bits of A-D conversion result
• During 8-bit mode
When read, the content is indeterminate
Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if
read, turns out to be “0”.
