12.3 Wakeup Function

The wakeup function allows you to turn the BHT on at the wakeup time (of the system clock)

specified in user programs.

To set the wakeup time, use the

TIME$ function as follows:

(1) Set 1 to bit 2 on port 8. Switches the TIME$ function to the setting of the

wakeup time.

(2) Set the wakeup time by using the

TIME$ function.

(3) Set 1 to bit 0 on port 8. Activates the wakeup function.

To confirm the preset wakeup time, use the TIME$ function as follows:

(1) Set 1 to bit 2 on port 8. Switches the TIME$ function to the setting of the

wakeup time.

(2) Retrieve the wakeup time by using the

TIME$ function.

TIP

If you set or retrieve the system time or wakeup time by using the TIME$ function,

then the value of bit 2 on port 8 will be automatically reset to zero.

When bit 2 on port 8 is zero, you can set or retrieve the current system time by using

the TIME$ function.

By reading the value of bit 1 on port 8 in user programs, you may confirm the initia-

tion option of the BHT. If this bit is 1, it means that the BHT is initiated by the

wakeup function and if 0, it means that it is initiated by the PW key.
