INT_CLR0
21.3.54 INT_CLR0
This register enables the individual interrupt sources’ ability to clear posted interrupts.
When bits in this register are read, a ‘1’ is returned for every bit position that has a corresponding posted interrupt. When bits
in this register are written with a ’0’ and ENSWINT is not set, posted interrupts are cleared at the corresponding bit positions.
If there is no posted interrupt, there is no effect. When bits in this register are written with a ’1’ and ENSWINT is set, an inter-
rupt is posted in the interrupt controller .
