20.3.33 INT_CLR0
This register is used to enable the individual interrupt sources’ ability to clear posted interrupts.
When bits in this register are read, a ‘1’ will be 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 will be cleared at the corresponding bit
positions. If there was not a posted interrupt, there is no effect. When bits in this register are written with a ’1’ and ENSWINT
is set, an interrupt is posted in the interrupt controller .
