Section 16 A/D Converter
To Change the Buffer Operation
Suspend the conversion wait state or conversion, and clear the BUFE1 and BUFE0 bits to B'00.
When the BUFE1 and BUFE0 bits are set and conversion is restarted, the buffer operation shown
in table 16.4 will be performed.
16.4.6
In simultaneous sampling operation, the input voltages of two channels are sampled
simultaneously, and continuous conversion is performed. Simultaneous sampling operation is
enabled in group mode. The channels involved in simultaneous sampling operation are determined
by bits CH2 and CH1. The combinations of these bits are shown in table 16.5.
For example, simultaneous sampling will be performed when CH2 and CH1 = B'11, on channel
pairs AN
sampling timing is shown in figure 16.8.
