TMP86PM29BUG
13. 10-bit AD Converter (ADC)
The TMP86PM29BUG have a 10-bit successive approximation type AD converter.
13.1 Configuration
The circuit configuration of the 10-bit AD converter is shown in Figure 13-1.
It consists of control register ADCCR1 and ADCCR2, converted value register ADCDR1 and ADCDR2, a DA
converter, a sample-hold circuit, a comparator, and a successive comparison circuit.
Note: Before using AD converter, set appropriate value to I/O port register conbining a analog input port. For details, see the sec-
tion on "I/O ports".
