5.6.4
Table 5.4 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 5.4 are explained in table 5.5.
This LSI is capable of fast word transfer to on-chip memory, and have the program area in on-chip
ROM and the stack area in on-chip RAM, enabling high-speed processing.

Notes: 1. Two states in case of internal interrupt.
