Operation after reset

releasing

The option is specified until 3ms after

going to a ‘H’ level to the reset

terminal by degrees. The program is

executed from 00H of the program

counter.

The program is executed from 00H of

the program counter immediately after

going to a ‘H’ level to the reset

terminal.
