14.5.1 Interrupt Register (IR, TIMER0: T0IR - 0xE000 4000 and TIMER1: T1IR
- 0xE000 8000)
The Interrupt Register consists of four bits for the match interrupts and four bits for the
capture interrupts. If an interrupt is generated then the corresponding bit in the IR will be
high. Otherwise, the bit will be low. Writing a logic one to the corresponding IR bit will reset
the interrupt. Writing a zero has no effect.
