Note 1: This applies when using one D-A converter, with the D-A register for the unused D-A converter set to
“0016”. The A-D converter's ladder resistance is not included.
Also, when DA register contents are not “00”, the current IVREF always flows even though Vref may
have been set to be “unconnected” by the A-D control register.
Note 2: 10 MHZ for the mask ROM version and flash memory 5V version.
