5.4.5
The chip is capable of fast word transfer instruction to on-chip memory, and the program area is
provided in on-chip ROM and the stack area in on-chip RAM, enabling high-speed processing.
Table 5-9 shows interrupt response times - the interval between generation of an interrupt request
and execution of the first instruction in the interrupt handling routine. The execution status
symbols used in table 5-9 are explained in table 5-10.
