Register 19: PWM0 Interrupt Status and Clear (PWM0ISC), offset 0x04C PWM1
Interrupt Status and Clear (PWM1ISC), offset 0x08C 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
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
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.
