BS801C Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the BS801C?
  The maximum operating frequency of the BS801C is 16 MHz, as specified in the datasheet. However, it's recommended to operate it at 12 MHz or lower for optimal performance and power consumption.
• How do I implement watchdog timer (WDT) reset in BS801C?
  To implement WDT reset, you need to enable the WDT function by setting the WDTE bit in the watchdog timer control register (WTCSR). Then, you need to periodically clear the WDT flag by writing '0' to the WDTCR register. If the WDT flag is not cleared within the specified timeout period, the BS801C will reset.
• What is the purpose of the brown-out detection (BOD) function in BS801C?
  The BOD function in BS801C is used to detect when the VCC supply voltage falls below a certain threshold (typically 2.5V). When this happens, the BS801C will reset to prevent incorrect operation or data corruption. You can enable or disable BOD by setting the BODEN bit in the configuration register (CONFIG).
• How do I use the internal oscillator in BS801C?
  To use the internal oscillator in BS801C, you need to set the OSCEN bit in the oscillator control register (OSCCR). Then, you need to select the desired oscillator frequency by setting the FREQ bits in the OSCCCR register. Finally, you need to wait for the oscillator to stabilize before using it as the system clock.
• What is the maximum current consumption of BS801C in sleep mode?
  The maximum current consumption of BS801C in sleep mode is typically around 10-20 uA, depending on the specific operating conditions and configuration. This is much lower than the current consumption in active mode, which can be up to several milliamps.
