Register 13: PWM0 Interrupt Status and Clear (PWM0ISC), offset 0x04C
This register provides the current set of interrupt sources that are asserted to the controller. Bits set
to 1 indicate the latched events that have occurred; bits set to 0 indicate 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.
Comparator B Down Interrupt
Indicates that the counter has matched the comparator B value while
counting down.
Comparator B Up Interrupt
Indicates that the counter has matched the comparator B value while
counting up.
Comparator A Down Interrupt
Indicates that the counter has matched the comparator A value while
counting down.
Comparator A Up Interrupt
Indicates that the counter has matched the comparator A value while
counting up.
Counter=Load Interrupt
Indicates that the counter has matched the PWMnLOAD register.
Counter=0 Interrupt
Indicates that the counter has matched 0.
