CHAPTER 10 INTERRUPT FUNCTIONS10.3 Interrupt Function Control RegistersThe interrupt functions are controlled by the following four types of registers.• Interrupt request flag registers 0 and 1 (IF0 and IF1)• Interrupt mask flag registers 0 and 1 (MK0 and MK1)• External interrupt mode register 0 (INTM0)• Program status word (PSW)Table 10-2 lists interrupt requests, the corresponding interrupt request flags, and interrupt mask flags.Table 10-2.
