22.3.5 Interrupts

Table 22-5. Available Interrupt Vectors and Sources in Normal Mode
Name	Vector Description	Conditions
OVF	Overflow or underflow interrupt	The counter has reached TOP or BOTTOM
CMP0	Compare Channel 0 interrupt	Match between the counter value and the Compare 0 register
CMP1	Compare Channel 1 interrupt	Match between the counter value and the Compare 1 register
CMP2	Compare Channel 2 interrupt	Match between the counter value and the Compare 2 register

Table 22-6. Available Interrupt Vectors and Sources in Split Mode
Name	Vector Description	Conditions
LUNF	Low-byte Underflow interrupt	Low byte timer reaches BOTTOM
HUNF	High-byte Underflow interrupt	High byte timer reaches BOTTOM
LCMP0	Compare Channel 0 interrupt	Match between the counter value and the low byte of the Compare 0 register
LCMP1	Compare Channel 1 interrupt	Match between the counter value and the low byte of the Compare 1 register
LCMP2	Compare Channel 2 interrupt	Match between the counter value and the low byte of the Compare 2 register

When an interrupt condition occurs, the corresponding interrupt flag is set in the peripheral’s Interrupt Flags (peripheral.INTFLAGS) register.

An interrupt source is enabled or disabled by writing to the corresponding enable bit in the peripheral’s Interrupt Control (peripheral.INTCTRL) register.

An interrupt request is generated when the corresponding interrupt source is enabled, and the interrupt flag is set. The interrupt request remains active until the interrupt flag is cleared. See the peripheral’s INTFLAGS register for details on how to clear interrupt flags.
