CHAPTER 17 DTP/EXTERNAL INTERRUPTS
17.3.2 DTP/External Interrupt Enable Register (ENIR1)
The DTP/external interrupt enable register (ENIR1) enables/disables the DTP/external
interrupt request in the external peripheral devices.
ENIR1 is corresponding to INT8, INT9R, INT10, INT11, INT12R, INT13, INT14R and
INT15R.

DTP/external interrupt
request enable bits
These bits enable or disable the DTP/external interrupt request to
the DTP/external interrupt channel.
If the DTP/external interrupt request enable bit (ENIR1:EN) and
the DTP/external interrupt request flag bit (EIRR1:ER) are set to
"1", the interrupt request is generated to the corresponding DTP/
external interrupt pin.
Reference:
The state of the DTP/external interrupt pin can be read
directly using the port data register irrespective of the setting
of the DTP/external interrupt request enable bit.
