CHAPTER 21 INTERRUPT AND TEST FUNCTIONS
21.3 Interrupt Function Control Registers
The following six types of registers are used to control the interrupt functions.
• Interrupt request flag register (IF0L, IF0H, IF1L)
• Interrupt mask flag register (MK0L, MK0H, MK1L)
• Priority specify flag register (PR0L, PR0H, PR1L)
• External interrupt mode register (INTM0, INTM1)
• Sampling clock select register (SCS)
• Program status word (PSW)
Table 21-2 gives a listing of interrupt request flags, interrupt mask flags, and priority specify flags corresponding
to interrupt request sources.
