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 a 32.768kHz crystal oscillator. Calculation of the frequency is based on
the system frequency sources as stated above. It is recommended that the host controller should ini-
tialize the HT1620 after power on reset, for power on reset may fail, which in turn leads to malfunc-
tioning of the HT1620.
