Figure 10.13 TXMR Register and TYZMR Register when INT1 and INT2 Interrupt Used
10.2.3 INT1 Interrupt and INT2 Interrupt
______
INT1 interrupts are triggered by INT1 inputs. The edge polarity can be selected with the R0EDG bit in
the TXMR register. The INT1 pin is shared with the CNTR0 pin.
______
INT2 interrupts are triggered by INT2 inputs. The edge polarity can be selected with the R1EDG bit in
the TYZMR register. The INT2 pin shared with the CNTR1 pin.
Figure 10.13 shows the TXMR and TYZMR registers when using INT1 and INT2 interrupts.
