SUB SOURCE PENDING (SUBSRCPND) REGISTER

You can clear a specific bit of the SUBSRCPND register by writing a data to this register. It clears only the bit

positions of the SUBSRCPND register corresponding to those set to one in the data. The bit positions

corresponding to those that are set to 0 in the data remains as they are.

SUBSRCPND 0X4A000018 R/W Indicate the interrupt request status.

0 = The interrupt has not been requested.

1 = The interrupt source has asserted the interrupt

request.
