APPLICATION

2-149

2.10 Reset circuit

____________

The reset state is caused by applying an “L” level to the RESET pin. After that, the reset state is released

____________

by applying an “H” level to the RESET pin, so that the program is executed in the middle-speed mode from

the contents of the reset vector address.

2.10.1 Connection example of reset IC

Figure 2.10.1 shows the example of power-on reset circuit. Figure 2.10.2 shows the system example which

switches to the RAM backup mode by detecting a drop of the system power source voltage with the INT

interrupt.
