If an external clock is selected as the source of
system frequency, the SYS DIS command turns
out invalid and the power down mode fails to be
carried out until the external clock source is re-
moved.
Buzzer tone output
A simple tone generator is implemented in the
HT1623. The tone generator can output a pair
of differential driving signals on the BZ and BZ
which are used to generate a single tone.
Command format
The HT1623 can be configured by the software
setting. There are two mode commands to con-
figure the HT1623 resource and to transfer the
LCD display data.
The following are the data mode ID and the
command mode ID:

If successive commands have been issued, the
command mode ID can be omitted. While the
system is operating in the non-successive com-
mand or the non-successive address data mode,
the CS pin should be set to 1 and the previous
operation mode will be reset also. The CS pin
returns to 0 , a new operation mode ID should
be issued first.
