(4) A/D2 conversion result registers n, nH (AD2CRn, AD2CRnH)
Caution If a write operation is performed on the AD2M0, AD2M1, and AD2S registers, the contents of
The AD2CRn and AD2CRnH registers are registers that hold the A/D conversion results. Each time A/D
conversion ends, the conversion result is loaded from the successive approximation register (SAR) and stored
in the higher 10 bits of the AD2CRn register. The lower 6 bits of these registers are always 0 when read.
The higher 8 bits of A/D conversion result are read to the AD2CRnH register.
These registers can only be read in 16-bit or 8-bit units. When the A/D conversion results are read in 16-bit
units, the AD2CRn register is specified, and when the higher 8 bits are read, the AD2CRnH register is
specified.
Reset sets AD2CRn register to 0000H and AD2CRnH register to 00H.
The correspondence between the analog input pins and the AD2CRn and AD2CRnH registers is shown below.
