Registers Controlling Interrupt Function; Flags Corresponding To Interrupt Request Signal Names - NEC PD789488 User Manual

16.3 Registers Controlling Interrupt Function

The following five types of registers are used to control the interrupt functions.
• Interrupt request flag registers (IF0 to IF2)
• Interrupt mask flag registers (MK0 to MK2)
• External interrupt mode registers (INTM0 and INTM1)
• Program status word (PSW)
• Key return mode registers (KRM00, KRM01)
Table 16-3 gives a listing of interrupt request flag and interrupt mask flag names corresponding to interrupt
requests.
