320h
EOI
End-Of-Interrupt
Used to clear the in-service bit of an interrupt
that is currently in service.
322h
POLL
Poll
Indicates the interrupt type of the highest
priority pending interrupt.
324h
POLLST
Poll Status
Copy of the POLL register. Reading the Poll
Status register has no effect on the rest of the
system.
326h
IMASK
Interrupt Mask
Contains the mask bits for interrupt channels
0–14. These are the same physical mask bits
that exist in all of the Channel Control registers,
but here all channels are accessible at one
time.
328h
PRIMSK
Priority Mask
Determines the minimum priority required for
a maskable interrupt source to be requested.
32Ah
INSERV
In-Service
Indicates which channels are in-service—the
channel’s interrupt service routine is active.
32Ch
REQST
Interrupt Request
Indicates which channels have pending
requests.
32Eh
INTSTS
Interrupt Status
Indicates the status of the General-Purpose
DMA and Timer interrupt channels.
330h
DMAHLT
DMA Halt
Contains the DHLT bit which, when Set, halts
all DMA activity. This bit is set by an NMI, and
cleared by any IRET instruction. This bit can
be read or written by software.
