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, a 32.768kHz
crystal oscillator, or an external 32kHz clock. Calculation of the frequency is based on the sys-
tem frequency sources as stated above. It is recommended that the host controller should ini-
tialize the HT1626 after power on reset, for power on reset may fail, which in turn leads to the
malfunctioning of the HT1626.
