dsPIC33FJ32MC302/304, dsPIC33FJ64MCX02/X04 AND dsPIC33FJ128MCX02/X04
11.7 Peripheral Pin Select Registers
The dsPIC33FJ32MC302/304, dsPIC33FJ64MCX02/
X04 and dsPIC33FJ128MCX02/X04 family of devices
implement 33 registers for remappable peripheral
configuration:
• 20 Input Remappable Peripheral Registers:
- RPINR0-RPINR1, RPINR3-RPINR4,
RPINR7, RPINR10-RPINR21, PRINR23, and
PRINR26
• 13 Output Remappable Peripheral Registers:
- RPOR0-RPOR12
Note:
Input and Output Register values can only
be changed if the IOLOCK bit
(OSCCON<6>) is set to ‘0’. See
Section 11.6.3.1 “Control Register
Lock” for a specific command sequence.
