4.3.6
Table 4.4 indicates the number of states that elapse from an interrupt request signal until the first
instruction of the software interrupt-handling routine is executed. Since on-chip memory is
accessed 16 bits at a time, very fast interrupt service can be obtained by placing interrupt-handling
routines in on-chip ROM and the stack in on-chip RAM.
