The maximum clock frequency of the MC9S08SH8CSC is 20 MHz.
The internal clock source of the MC9S08SH8CSC can be configured using the SYNR and REFS registers in the System Options Register (SOR) module.
The COP module is a watchdog timer that resets the microcontroller if it does not receive a 'service' pulse within a specified time period, indicating that the software is not operating properly.
The ADC module in the MC9S08SH8CSC can be used by configuring the ADC control registers, selecting the analog input channel, and starting the conversion process using the ADCSC1 register.
The maximum current that can be sourced or sunk by the GPIO pins of the MC9S08SH8CSC is 25 mA.
