Register 19: PWM0 Interrupt Status and Clear (PWM0ISC), offset 0x04C
Register 20: PWM1 Interrupt Status and Clear (PWM1ISC), offset 0x08C
Register 21: PWM2 Interrupt Status and Clear (PWM2ISC), offset 0x0CC
These registers provide the current set of interrupt sources that are asserted to the controller
(PWM0ISC controls the PWM generator 0 block, and so on). Bits set to 1 indicate the latched
events that have occurred; a 0 bit indicates that the event in question has not occurred. These are
R/W1C registers; writing a 1 to a bit position clears the corresponding interrupt reason.

Description
Reserved bits return an indeterminate value, and should
never be changed.
Indicates that the counter has matched the comparator B
value while counting down.
Indicates that the counter has matched the comparator B
value while counting up.
Indicates that the counter has matched the comparator A
value while counting down.
Indicates that the counter has matched the comparator A
value while counting up.
Indicates that the counter has matched the PWMnLOAD
register.
Indicates that the counter has matched 0.
