6. INTERRUPT FUNCTION
There are 10 interrupts, classified into two types, for different interrupt sources.
Nonmaskable interrupt : 1 source
Maskable interrupts
: 9 sources

Notes 1.
The priority regulates which maskable interrupt is higher, when two or more maskable interrupts are
requested simultaneously. Zero signifies the highest priority, while 8 is the lowest.
2.
Basic configuration types (A), (B), and (C) correspond to (A), (B), and (C) in Figure 6-1, respectively.
