Example of an automotive system. The V
SYS
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
V
DD
, 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 Pin Functions, INT.) In addition, reading the Status Register before delayed alarm acti-
vates will disable alarm signal.
