3. ISP0, ISP1, and IE are flags contained in the PSW.
4. PR is a flag contained in the PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR10L, PR10H, PR11L,
ISP1 = 0, ISP0 = 0: An interrupt of level 1 or level 0 is being serviced.
ISP1 = 0, ISP0 = 1: An interrupt of level 2 is being serviced.
ISP1 = 1, ISP0 = 0: An interrupt of level 3 is being serviced.
ISP1 = 1, ISP0 = 1: Wait for An interrupt acknowledgment.
IE = 0: Interrupt request acknowledgment is disabled.
IE = 1: Interrupt request acknowledgment is enabled.
