This section describes the 8-bit analog-to-digital converter (ADC).
Features of the ADC module include:
Fifteen ADC channels are available in the 52-PLCC
(MC68HC708AS48CFN) for sampling external sources at pins
PTD6/ATD14/TCLK
Sixteen ADC channels are available in the 64-QFP (engineering sample)
for sampling external sources at pins PTD7/ATD15
PTB7/ATD7
converter to select one of the ADC channels as ADC voltage input
(ADCVIN). ADCVIN is converted by the successive approximation
register-based counters. When the conversion is completed, ADC
places the result in the ADC data register and sets a flag or generates
an interrupt. (See
