MC908LJ12CFBE Frequently Asked Questions (FAQs)

The maximum clock frequency that can be used with the internal oscillator is 4 MHz. However, it's recommended to use a crystal oscillator for more accurate and stable clock signals.
The watchdog timer can be configured using the WDTCSR register. Set the WDTON bit to enable the watchdog timer, and set the WDP bits to select the timeout period. You can also use the WDTCSR register to clear the watchdog timer.
The BPROT fuse is used to protect the boot loader section of the flash memory from accidental writes. When the BPROT fuse is programmed, the boot loader section is protected, and any attempts to write to it will be ignored.
The ADC on the MC908LJ12CFBE is a 10-bit successive approximation ADC. To use it, configure the ADC control register (ADCCFG) to select the input channel, set the ADC clock, and enable the ADC. Then, start the conversion by setting the ADCCFG register, and wait for the conversion to complete. The result can be read from the ADC data register (ADC_DR).
The maximum current that can be sourced or sunk by the GPIO pins is 25 mA. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation.
