Interrupt status of GPIO - X
Read ‘1’ if state transition is detected in corresponding GPIO channel
Write’1’ to clear the interrupt staus.
Interrupt status of PWM – X.
Read ‘1’ if the corresponding PWM channel complete programmed sequence
Write ‘1’ to clear the interrupt status
0x0C – 0x0D
R/W
0x0000
This register is used to enable the generation of interrupt signal, at the INT pin.
0x0E
R/W
0x00
When a PWM controller completes the PWM sequence, the corresponding bit in this
register goes to ‘1’. Write ‘1’ in this register clears the written bit, writing ‘0’ has no
effect.
