23.8 I/O Registers
23.8.1 ADC Status and Control Register
MC68HC908AS60 — Rev. 1.0
Address:
These I/O registers control and monitor ADC operation:
The following paragraphs describe the function of the ADC status and
control register.
COCO — Conversions Complete Bit
Reset:
Read:
Write:
•
•
•
When the AIEN bit is a logic 0, the COCO is a read-only bit which is
set each time a conversion is completed. This bit is cleared whenever
the ADC status and control register is written or whenever the ADC
data register is read.
If the AIEN bit is a logic 1, the COCO is a read/write bit which selects
the CPU to service the ADC interrupt request. Reset clears this bit.
