Jul 2, 2010
When a write operation is performed to A/D converter mode register (ADM), A/D converter mode register 1 (ADM1),
analog input channel specification register (ADS), and A/D port configuration register (ADPC), the contents of ADCR
and ADCRH may become undefined. Read the conversion result following conversion completion before writing to
ADM, ADM1, ADS, or ADPC. Using a timing other than the above may cause an incorrect conversion result to be
read.
The equivalent circuit of the analog input block is shown below.
Remarks 1. The resistance and capacitance values shown in Table 10-8 are not guaranteed values.
Rewriting DACSWn (n = 0, 1) during A/D conversion is prohibited when both the positive reference voltage of A/D
converter (AD
