MC9S08AC96CFGE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 16 MHz, but it's recommended to use 8 MHz or lower for optimal performance and to minimize power consumption.
• How do I configure the watchdog timer to reset the MCU in case of a fault?
  To configure the watchdog timer, you need to set the WDTCLK register to select the clock source, set the WDTCNT register to set the timeout period, and enable the watchdog timer by setting the WDTEN bit in the WDTCTL register.
• Can I use the ADC in differential mode with an external reference voltage?
  Yes, the ADC can be used in differential mode with an external reference voltage. You need to configure the ADC to use an external reference voltage by setting the ADCCFG register, and then configure the differential input channels using the ADCMUX register.
• How do I implement a low-power mode with the MCU?
  To implement a low-power mode, you can use the STOP or WAIT instructions to put the MCU into a low-power state. You can also use the Power Management Module (PMM) to control the power modes and reduce power consumption.
• Can I use the SCI module for UART communication with a baud rate higher than 115200 bps?
  No, the SCI module is limited to a maximum baud rate of 115200 bps. If you need a higher baud rate, you may need to use an external UART chip or a different communication protocol.
