Example of an automotive system. The VSYS and LINE inputs can be used to sense the ignition turning on and off. An
external switch is included to activate the system without turning on the ignition. Also, the CMOS CPU is not powered down
with the system VDD, but is held in a low power reset mode during power down. When restoring power the CDP68HC68T1
will enable the CLK OUT pin and set the PSE and CPUR high.
Important Application Note: Those units with a code of 6PG have delayed alarm interrupts of 8.3ms regardless of
CDP68HC68T1’s operating frequency. (See "Functional Description", INT on page 10.) In addition, reading the Status
Register before delayed alarm activates will disable alarm signal.
