R-IN32M3-EC User's Manual 8. Port Function
8.7 Trigger-Synchronous Ports (RP00 to RP37)
The state of the 32-bit port pins RP00 to RP37 can be updated in synchronization with an interrupt from an on-chip
peripheral function.
Use the RPTRGMD register to set trigger-synchronous port control mode in 1-bit units. To select the target trigger, use
the RPTFR0 to RPTFR3 registers.
For details, see the R-IN32M3 Series User's Manual (Peripheral Modules).
