Description
Clears masking of IRL3 to
IRL0 interrupt sources
when IRL3 to IRL0 operate
as an encoded interrupt
input.
Clears masking of IRL7 to
IRL4 interrupt sources
when IRL7 to IRL4 operate
as an encoded interrupt
input.
Reserved
These bits are always read as 0. The write value should
always be 0.
