Description
64-TQFP
Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output
ST = Schmitt Trigger input with CMOS levels Analog = Analog input
I = Input O = Output
P = Power OD = Open-Drain (no P diode to V
DD)
Note 1: Default assignment for ECCP2/P2A when CCP2MX Configuration bit is set.
2: Alternate assignment for ECCP2/P2A when CCP2MX Configuration bit is cleared.
3: RA7 and RA6 will be disabled if OSC1 and OSC2 are used for the clock function.
