indicates
the command mode ID. If successive commands have been issued, the command mode ID ex-
cept for the first command will be omitted. The source of the tone frequency and of the time
base/WDT clock frequency can be derived from an on-chip 32kHz RC oscillator or an external
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 HT1627 after power on
reset, for power on reset may fail, which in turn leads to the malfunctioning of the HT1627.
