18f452 address question

[leevise]

hello,guys

There is a question, the detail is as follow:

The PORTC register address F82h
but the "18f452.h" set the PIN_C0 address 31760.

This why ? the F82h ---->decimal 3970 not equal to 31760
Who can tell me the reason?

Thank you very much.

Pin 'C0',, is only one pin of port C.
Now think - how can I code a pin 'number' and a port address together?.
Answer - take port pin number (0). Take port address (F82). Multiply address by 8 - 31760. Add pin number - 31760.

Best Wishes
