converter, a sample-hold circuit, a comparator, and a successive comparison circuit.
The TMP86FH46BNG have a 10-bit successive approximation type AD converter.
The circuit configuration of the 10-bit AD converter is shown in Figure 12-1.
It consists of control register ADCCR1 and ADCCR2, converted value register ADCDR1 and ADCDR2, a DA
Note:Before using AD converter, set appropriate value to I/O port register combining a analog input port. For de-
