µPD77210, 77213
7.1.2 Interrupt vector table
Addresses 0x200 to 0x23F of the instruction memory are assigned to entry points (vectors) of interrupts. Four
instruction addresses are assigned to each interrupt source.
Four interrupt sources are assigned to each interrupt vector. There are 12 vectors. By identifying the source in
the vector, the µPD77210 can use 38 interrupt sources and µPD77213 can use 42 interrupt sources.
Each of these interrupt sources can be masked by using the interrupt control register (ICR0 to ICR11).

These interrupt sources are for the µPD77213 only. When using the µPD77210, they are reserved.
Cautions
1. Reset is not an interrupt but is used as an entry of a vector.
2. It is recommended that the vector of an interrupt source that is not used branch to an
abnormality processing routine.
