I have completed rotary encoder configuration to toggle led to other pin of pic32mx575f256h.
in given datasheet (diagram is below ) i have configure micro controller pin no. 2 & 3 (RE6 AND RE7) to the encoder. and output to pin no.64 % 63 (RE3 AND RE4). every thing working right. but when i chenged encoder to pin no. 17 & 18 (RB6 AND RB7) so output to led is not toggling.
and i also marked that even i try to all black part (means 5v tolerant) of pic pin as a input of encoder then working perfectly .

hear is the code .
that working perfect but not other port like portb and also configured portb as same as port e.
