Note:
X stands for don t care
A9~A0: RAM address
D3~D0: RAM data
D/C: Data/Command mode
Def.: Power-on reset default
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 tone frequency source and the time base/WDTclock frequency source can be derived from an
on-chip 32kHz RC oscillator, a 32.768kHz crystal oscillator, or an external 32kHz clock. Calculation of the fre-
quency is based on the system frequency sources as stated above. It is recommended that the host controller
should initialize the HT1660 after power-on reset, otherwise, power on reset may fail, which in turn leads to the
malfunctioning of the HT1660.
