(6) A/D2 conversion result registers 0 to 7, 0H to 7H (ADA2CR0 to ADA2CR7, ADA2CR0H to ADA2CR7H)
The ADA2CRn and ADA2CRnH registers are registers that hold the A/D conversion results. Each time A/D
conversion ends, the conversion result is loaded from the conversion register (SAR) to this register. The
conversion result is stored in the higher 8 bits or 10 bits of the ADA2CRn register at the resolution (8 bits or 10
bits) specified by the ADA2CTL1 register. The lower 7 bits or 5 bits of the ADA2CRn register are always 0
when read.
For the ADA2CRnH register, the higher 8 bits of the A/D conversion result are read.
These registers are read-only, in 16-bit or 8-bit units. During this register is read in 16-bit units, the ADA2CRn
register is specified, and during higher 8 bits are read, the ADA2CRnH register is specified.
Reset sets these registers to 0000H.
