0x0E 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 Interrupt Flags register of the peripheral (peripheral.INTFLAGS).

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

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.
