• 6-source 2-priority level

Interrupt and multi-level

Interrupt available by programming IP and IE registers

• Memory-mapped special function registers

• Bit addressable data memory and SFRs

• Minimum instruction cycle

: 545 ns @ 22 MHz operation

• "Multiply"/"divide" instruction cycle

• Standby functions

: Power-down mode (oscillator stop)

Activated by software or hardware; provid-

ing ports with floating or active status

The software power-down stet mode is ter-

minated by interrupt signal enabling execu-

tion from the interrupted address.
