16. 10-bit AD Converter (ADC)
16.1 Configuration
converter, a sample-hold circuit, a comparator, and a successive comparison circuit.
The TMP88CS43FG have a 10-bit successive approximation type AD converter.
It consists of control register ADCCRA and ADCCRB, converted value register ADCDRH and ADCDRL, a DA
Note: Before using AD converter, set appropriate value to I/O port register conbining a analog input port. For details, see the sec-
The circuit configuration of the 10-bit AD converter is shown in Figure 16-1.
