Operation after reset

releasing

The option is specified until 3ms after

going to a ‘H’ level to the reset terminal by

dgrees.

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 reset terminal.
