All the bold forms, namely
1 1 0
,
1 0 1
, and
1 0 0
, are mode commands. Of these,
1 0 0
indicates the
command mode ID. If successive commands have been issued, the command mode ID except for the
first command will be omitted. The source of the tone frequency and of the time base/WDT clock fre-
quency can be derived from an on-chip 32kHz RC oscillator, a 32.768kHz crystal oscillator, or an ex-
ternal 32kHz clock. Calculation of the frequency is based on the system frequency sources as stated
above. It is recommended that the host controller should initialize the HT1623 after power on reset,
for power on reset may fail, which in turn leads to the malfunctioning of the HT1623.
