Register Name
Register Function
PAGE REGISTER
A 4-bit register that supports paging.
INTR. READ
CLEAR
Reading this register clears all the pending edge sensitive
interrupts.
INTR.
EDGE/LEVEL
Define interrupt input as level or edge sensitive.
INTR. MASK
Mask selected interrupt input.
INTR.
REQUEST LATCH
A
“
1
”
in the register indicates the corresponding interrupt is
pending.
INTR.
PRIORITY STATUS
The register indicates which pending interrupt has the highest
priority.
1. Configures the PSD SRAM to be accessed by
“
PSEN
”
as
program space (8031 design).
2. Enable the Peripheral I/O Mode of Port A.
VM
PMMR0
PMMR1
