10.4.3
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. PIC24H devices include three features to
prevent alterations to the peripheral map:
• Control register lock sequence
• Continuous state monitoring
• Configuration bit pin select lock
10.4.3.1
Under normal operation, writes to the RPINRx and
RPORx registers are not allowed. Attempted writes
appear to execute normally, but the contents of the
registers remain unchanged. To change these
registers, they must be unlocked in hardware. The
register lock is controlled by the IOLOCK bit
(OSCCON<6>). Setting IOLOCK prevents writes to
the control registers; clearing IOLOCK allows writes.
To set or clear IOLOCK, a specific command sequence
must be executed:
1.
2.
3.
Unlike the similar sequence with the oscillator’s LOCK
bit, IOLOCK remains in one state until changed. This
allows all of the peripheral pin selects to be configured
with a single unlock sequence followed by an update to
all control registers, then locked with a second lock
sequence.

10.4.3.2
In addition to being protected from direct writes, the
contents of the RPINRx and RPORx registers are
constantly monitored in hardware by shadow registers.
If an unexpected change in any of the registers occurs
(such as cell disturbances caused by ESD or other
external events), a configuration mismatch Reset will
be triggered.
10.4.3.3
As an additional level of safety, the device can be
configured to prevent more than one write session to
the RPINRx and RPORx registers. The IOL1WAY
(FOSC<IOL1WAY>) configuration bit blocks the
IOLOCK bit from being cleared after it has been set
when.
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session. Programming
IOL1WAY allows user applications unlimited access
(with the proper use of the unlock sequence) to the
peripheral pin select registers.
10.5
The PIC24HJ12GP201/202 devices implement 17
registers for remappable peripheral configuration:
• Input Remappable Peripheral Registers (9)
• Output Remappable Peripheral Registers (8)
Note:
Peripheral Pin Select Registers
Input and Output Register values can only
be changed if OSCCON<IOLOCK> = 0.
See Section 10.4.3.1 “Control Register
Lock” for a specific command sequence.
