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 this register indicates the corresponding interrupt is
pending.
INTR.
PRIORITY STATUS
This register indicates which pending interrupt has the highest
priority.
1. Configures the ZPSD5XX SRAM to be accessed by
PSEN
as program space (8031 design).
2. Enables the Peripheral I/O Mode of Port A.
VM
PMMR0
PMMR1
Power management registers; enable the ZPSD5XX Power Down
Mode and other power saving configurations.
STATUS FLAGS
Counter/Timer Freeze Acknowledge bits.
GLOBAL
COMMAND
Specifies the Counter/Timer operation mode; and to start or stop
the Counter/Timers.
DLCY
Specifies the delay cycles to the Counter/Timers.
SOFTWARE
LOAD/STORE
This register enables a load (to the Counter/Timer) or store
(in the Image Register) operation.
FREEZE
COMMAND
This register disables the timer state-machine before access to
the Image Register is allowed.
CMD3 – 0
Command Registers for the configuration of the Counter/Timers.
CNTR3 – 0
