  • Page 34: Programming Considerations

    BS83A02L/BS83B04L Ultra-Low Power Touch Key Flash MCU Programming Considerations Care must be taken that data is not inadvertently written to the EEPROM. Protection can be enhanced by ensuring that the Write Enable bit is normally cleared to zero when not writing. Also the Bank Pointer could be normally cleared to zero as this would inhibit access to Bank 1 where the EEPROM control register exist.

  • Page 35: Oscillators

    There are two methods of generating the system clock, one high speed oscillator and one low speed oscillator. For the BS83A02L, the high speed oscillator is the internal 8MHz RC oscillator, HIRC. For the BS83B04L, the high speed oscillator is the internal 2/4/8MHz RC oscillator. The low speed oscillator is the internal 2kHz RC oscillator, LIRC.

  • Page 36: Internal High Speed Rc Oscillator - Hirc

    The internal RC oscillator is a fully integrated system oscillator requiring no external components. For the BS83A02L, the internal RC oscillator has a fixed frequency of 8MHz. For the BS83B04L, the internal RC oscillator has three fixed frequencies of 2MHz, 4MHz and 8MHz, which is selected using a configuration option.

  • Page 37: Operating Modes And System Clocks

    As Holtek has provided these devices with both high and low speed clock sources and the means to switch between them dynamically, the user can optimise the operation of their microcontroller to achieve the best performance/power ratio.

  • Page 38: System Operation Modes

    BS83A02L/BS83B04L Ultra-Low Power Touch Key Flash MCU System Operation Modes There are six different modes of operation for the microcontroller, each one with its own special characteristics and which can be chosen according to the specific performance and power requirements of the application. There are two modes allowing normal operation of the microcontroller, the FAST Mode and SLOW Mode.

  • Page 39: Control Registers

    BS83A02L/BS83B04L Ultra-Low Power Touch Key Flash MCU IDLE1 Mode The IDLE1 Mode is entered when a HALT instruction is executed and when the FHIDEN bit in the SCC register is high and the FSIDEN bit in the SCC register is high. In the IDLE1 Mode the CPU will be switched off but both the high and low speed oscillators will be turned on to provide a clock source to keep some peripheral functions operational.

    BS83A02L/BS83B04L Ultra-Low Power Touch Key Flash MCU There is only one method of using software instruction to clear the Watchdog Timer. That is to use the single “CLR WDT” instruction to clear the WDT contents. The maximum time out period is when the 2 division ratio is selected.
