+ 0.3V without damage. For accurate
conversions the inputs should not extend beyond the
supply rails.
Transfer Function
Figure 7 shows the bipolar two

s complement ADC
transfer function. The single-ended conversion range
extends from -V

/2 to +V
REF
/2, where V
REF
= V

- V
REF-
. The differential conversion range extends from
-V
REF
to +V
REF
. Each LSB in the single-ended and dif-
ferential mode reflects voltage increments of V
REF
/4096
and 2V
REF
/4096, respectively.
ADC Special Function Registers
The ADCON or A/D Control SFR establishes ADC oper-
ating conditions and input configurations. Table 7
shows the individual bit functions. A
“
write
”
to ADCON
initiates the A/D conversion process.

General Flag 1. General-purpose flag for software control.
General Flag 0. General-purpose flag for software control.
STOP Mode Select. STOP = 1 stops the crystal oscillator and powers down the analog circuitry.
0
IDLE
IDLE Mode Select. IDLE = 1 results in suspension of CPU processing.
