PIC18F1230/1330
15.1
The A/D conversion can be triggered by setting the GO/
DONE bit. This bit can either be set manually by the
programmer or by setting the SEVTEN bit of ADCON0.
When the SEVTEN bit is set, the Special Event Trigger
from the Power Control PWM module triggers the A/D
conversion. For more information, see Section 13.14
“PWM Special Event Trigger”.

Equation 15-1 may be used. This equation assumes
that 1/2 LSb error is used (1024 steps for the A/D). The
1/2 LSb error is the maximum error allowed for the A/D
