How is the HT47 R-F type MCU Buzzer setup?
• Choose PA0 and PA1 as CMOS output in the configuration options • Select Buzzer Mode in the configuration options • Select clock source (same as RTC, WDT and Time Base) in the configuration options • Select Buzzer frequency from the formula fBUZZER=fS/22~29 (fS is the clock source mentioned above) After these steps are taken, set PA0 and PA1 to control the Buzzer output. When PA0=0 and PA1=0, both BZ and BZ pins output; When PA0=0 and PA1=1, BZ pin outputs only; When PA0=1, both BZ and BZ pins no buzzer output. To utilize the Buzzer Mode in HT47C10L, the following process should be followed: • Select PA0 and PA1 as Buzzer output via the software options • Select Buzzer frequency via the software options from the formula fBUZZER=fS/22~29 (fS is the clock source mentioned above) After these steps are taken, set PA0 and PA1 to control the Buzzer output. When PA0=0 and PA1=0, both BZ and BZ pins output; When PA0=0 and PA1=1, BZ pin outputs only; When PA0=1, both BZ and BZ pins no buzzer o
