Buzzer tone output A simple tone generator is implemented in the HT1622. The tone generator can output a pair of differential driving signals on the BZ and BZ which are used to generate a single tone. Command format The HT1622 can be configured by the software setting. There are two mode commands to con- figure the HT1622 resource and to transfer the LCD display data. The following are the data mode ID and the command mode ID: Operation Mode ID READ Data 1 1 0 WRITE Data 1 0 1 READ-MODIFY-WRITE Data 1 0 1 COMMAND Command 1 0 0 If successive commands have been issued, the command mode ID can be omitted. While the system is operating in a non-successive com- mand or a non-successive address data mode, the CS pin should be set to "1" and the previous operation mode will be reset also. The CS pin returns to "0", a new operation mode ID should be issued first. Name Command Code Function TONE OFF 0000-1000-X Turn-off tone output TONE 4K 010X-XXXX-X Turn-on tone output, tone frequency is 4kHz TONE 2K 0110-XXXX-X Turn-on tone output, tone frequency is 2kHz |
