The maximum operating frequency of the MC9S12DG128BMFU is 25 MHz, but it can be overclocked to 30 MHz with some limitations.
The clock source can be configured using the Clock Generation Module (CGM) registers. The CGM allows selection of the clock source, clock frequency, and clock mode. The default clock source is the internal oscillator, but it can be changed to an external clock source or the Phase-Locked Loop (PLL) clock source.
The COP module is a watchdog timer that monitors the MCU's operation and resets the device if it fails to respond within a specified time period. This is useful for detecting and recovering from software or hardware faults.
The ADC can be configured using the ADC registers. The ADC can operate in different modes, including single-shot mode, continuous conversion mode, and scan mode. The ADC can also be triggered by external events or software commands.
The maximum current that can be sourced or sunk by the MCU's I/O pins is 25 mA per pin, with a total current limit of 100 mA for all I/O pins combined.
