Note 1:
ADRS1
R/W-0
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).
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
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
