8.1.1.2
The ADC is capable of performing conversions using the MCU bus clock, the bus clock divided by two,
or the local asynchronous clock (ADACK) within the module. The alternate clock, ALTCLK, input for the
MC9S08QD4 series MCU devices is not implemented.
8.1.1.3
The ADC hardware trigger, ADHWT, is output from the real-time interrupt (RTI) counter. The RTI counter
can be clocked by either ICSERCLK or a nominal 32 kHz clock source within the RTI block.
The period of the RTI is determined by the input clock frequency and the RTIS bits. The RTI counter is a
free running counter that generates an overflow at the RTI rate determined by the RTIS bits. When the
ADC hardware trigger is enabled, a conversion is initiated upon a RTI counter overflow.
