23.3.5 Interrupts

Table 23-5. 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 23-6. 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.
