SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Interrupt Control
Descriptions are given here regarding how to enable or disable maskable interrupts and how to set the
priority to be accepted. What is described here does not apply to non-maskable interrupts.
Enable or disable a maskable interrupt using the interrupt enable flag (I flag), interrupt priority level selec-
tion bit, or processor interrupt priority level (IPL). Whether an interrupt request is present or absent is
indicated by the interrupt request bit. The interrupt request bit and the interrupt priority level selection bit
are located in the interrupt control register of each interrupt. Also, the interrupt enable flag (I flag) and the
IPL are located in the flag register (FLG).
Figure 1.11.3 shows the memory map of the interrupt control registers.
