PWM Interrupt Register (PWMIR - 0xE0014000)
The PWM Interrupt Register consists of eleven bits (Table 167), seven for the match interrupts and four reserved for the future
use. If an interrupt is generated then the corresponding bit in the PWMIR 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.
