The recommended oscillator crystal frequency for the MC908QB8MDTE is 16 MHz, but it can also operate with a 4 MHz or 8 MHz crystal with some limitations.
The internal clock source can be configured using the CLKSEL register. Set the CLKSEL bits to select the desired clock source, such as the internal oscillator, external oscillator, or PLL.
The maximum operating frequency of the MC908QB8MDTE is 20 MHz, but it can be overclocked to 24 MHz with some limitations and reduced reliability.
The watchdog timer can be enabled by setting the WDE bit in the WDTCSR register. The watchdog timer can be configured to reset the device or generate an interrupt when it times out.
The COP module is a watchdog timer that monitors the device's operation and resets it if it fails to periodically refresh the COP timer. This helps prevent the device from getting stuck in an infinite loop or malfunctioning.
