Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 4-0

ADRS<1:0>: A/D Result Buffer Depth Interrupt Select Control for Continuous Loop Mode bits

The ADRS bits are ignored in Single-Shot mode.

00 = Interrupt is generated when each word is written to the buffer

01 = Interrupt is generated when the 2nd and 4th words are written to the buffer

10 = Interrupt is generated when the 4th word is written to the buffer

11 = Unimplemented

Unimplemented: Read as ‘0’

SSRC<4:0>: A/D Trigger Source Select bits(1)

00000 = All triggers disabled

xxxx1 = External interrupt RC3/INT0 starts A/D sequence

xxx1x = Timer5 starts A/D sequence

xx1xx = Input Capture 1 (IC1) starts A/D sequence

x1xxx = CCP2 compare match starts A/D sequence

1xxxx = Power Control PWM module rising edge starts A/D sequence

Note 1: The SSRC<4:0> bits can be set such that any of the triggers will start a conversion (e.g., SSRC<4:0> = 00101

will trigger the A/D conversion sequence when RC3/INT0 or Input Capture 1 event occurs).
