(7) A/Dn conversion result registers 0 to 3, 0H to 3H (ADAnCR0 to ADAnCR3, ADAnCR0H to ADAnCR3H)
Table 12-3. Correspondence Between Analog Input Pins and ADAnCRm and ADAnCRmH Registers
(n = 0, 1)
The ADAnCRm and ADAnCRmH registers are registers that hold the A/D conversion results. Four of these
registers are provided per circuit, and two circuits are available.
conversion result is loaded from the successive approximation register (SAR) and stored in the higher 10 bits
of the ADAnCRm 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 ADAnCRmH 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 ADAnCRm register is specified, and when the higher 8 bits are read, the ADAnCRmH register is
specified.
Reset makes these registers undefined.
The correspondence between the analog input pins and the ADAnCRm and ADAnCRmH registers is shown
below.
