5. INTERRUPT FUNCTION
Interrupt Type Priority
Non-maskable
Maskable
Note Two types of watchdog interrupt sources (INTWDT), non-maskable and maskable, are available, and
Notes 1. If two or more maskable interrupts occur at the same time, they are acknowledged or kept pending
The PD178F098 has the following three types and 24 sources of interrupts:
• Non-maskable : 1
• Maskable
• Software
either of them can be selected.
