HOSTINTFLAG - Interrupt input register
The interrupt enable register enables or masks the interrupt n.
Interrupt n
The available interrupt of this device are defined in the first section of this chapter
under the key word "Interrupts".
The interrupt status bits of the two interrupt groups are treated differenctly:
•
INT[31:17] reflect the status of the group B interrupts, thus these bits
can only be read.
•
INT[15:0] reflect the status of the group A interrupts. These bits can
be set back to "0" by writing "1" to the concerned bit position.
Access
This register can be read/written in 32-bit units.
