RE7/AD15/

CCP2

RE7

DIG

LATE<7> data output.

PORTE<7> data input.

AD15(1)

DIG

External memory interface, address/data bit 15 output.(2)

TTL

External memory interface, data bit 15 input.(2)

CCP2(3)

DIG

CCP2 compare output and CCP2 PWM output; takes priority over

port data.

CCP2 capture input.

Legend:

O = Output, I = Input, DIG = Digital Output, ST = Schmitt Buffer Input, TTL = TTL Buffer Input, x = Don’t care (TRIS bit

does not affect port direction or is overridden for this option).

Note 1:

Available on 80-pin devices only.

External memory interface I/O takes priority over all other digital and PSP I/O.

Alternate assignment for CCP2 when CCP2MX Configuration bit is cleared (all devices in Microcontroller mode).
