Technical Data

ME — Mask Enable Bit
MFI — Mask Fast Interrupts Bit
MASK[4:0] — Interrupt Mask Field
The read/write ME bit enables interrupt masking. Reset clears ME.
The read/write MFI bit enables masking of fast interrupt requests.
Reset clears MFI.
The read/write MASK[4:0] field determines which interrupt priority
levels are masked. When the ME bit is set, all pending interrupt
requests at priority levels at and below the current MASK value are
masked. To mask all normal interrupts without masking any fast
interrupts, set the MASK value to 31 with the MFI bit cleared. See
