7.1.2 Interrupt vector table
instruction addresses are assigned to each interrupt source.
28
Addresses 0x200 through 0x23F of the instruction memory are entry points (vectors) of interrupts.
Cautions 1. Although reset is not an interrupt, it is handled like an interrupt as an entry to a vector.
2. It is recommended that unused interrupt source vectors be used to branch an error
3. Because a vector area also exists in the internal RAM area of the mask ROM model, this
processing routine.
area must be booted up.
address 0x200 must be booted up even when the internal instruction RAM and interrupts are
not used.
