10.1 Interrupt Function Types
10.2 Interrupt Sources and Configuration
PD78F951x, and up to four reset sources (see Table 10-1).
There are two types of interrupts: maskable interrupts and resets.
There are a total of seven maskable interrupt sources in PD78F921x, and six maskable interrupt sources in
Maskable interrupts
These interrupts undergo mask control. When an interrupt request occurs, the standby release signal occurs,
and if an interrupt can be acknowledged then the program corresponding to the address written in the vector
table address is executed (vector interrupt servicing). When several interrupt requests are generated at the
same time, processing takes place in the priority order of the vector interrupt servicing. For details on the
priority order, see Table 10-1.
There are external sources and internal sources of maskable interrupts.
Reset
The CPU and SFR are returned to their initial states by the reset signal.
occurrences are shown in Table 10-1.
When a reset signal occurs, program execution starts from the programs at the addresses written in addresses
0000H and 0001H.
PD78F921x: external sources: 2, internal sources: 5
