16.4.5
In buffer operation, when conversion ends on the channel concerned, at the same time as the
conversion result is stored in an ADDR register, the previously stored conversion result is
transferred to another ADDR register.
There is a choice of three kinds of buffer operation: a two-stage operation, AN0
ADDRB; dual two-stage operations, AN0
ADDRD; and a four-stage operation, AN0
When using buffer operation in combination with simultaneous sampling operation, set GRP=1,
BUFE1, BUFE0=B'10, and CH2=0.
Figure 16.7 shows buffer operation timing.
