RX23W Group 44. 12-Bit A/D Converter (S12ADE)
The value added by the A/D-converted value of the same channel is stored in bits 15 to 2.
Bits 1 and 0 are read as 0.
Flush-left format (A/D-converted value addition mode and 16-time conversion selected)
The value added by the A/D-converted value of the same channel is stored in bits 15 to 0.
When A/D-converted addition mode is selected, the value added by the A/D-converted value of the same channel is
indicated. The number of A/D conversions can be set to 1, 2, 3, 4, or 16 times. If A/D-converted addition mode is
selected, when the conversion count is set to 1 to 4 times, the value added by the A/D conversion result is retained in the
A/D data register as 2-bit extended data of the conversion accuracy bits; when the conversion count is set to 16 times, the
value added by the A/D conversion result is retained in the A/D data register as 4-bit extended data of the conversion
accuracy bits. Even if A/D-converted value addition mode is selected, the value is stored in the A/D data register
according to the settings of the A/D data register format select bits.
