13.3.3 Setting Values in the 8-bit Data Register (ADCR)
A value is set in the 8-bit data register via the data buffer (DBF) using the PUT instruction in the same way as for
comparison voltage setting in the single mode.
The peripheral address for the 8-bit data register (ADCR) of the A/D converter is assigned to 04H. If a value is
sent to ADCR by the PUT instruction, only the low-order 8 bits (DBF1, DBF0) of DBF are valid. DBF3 and DBF2 values
do not affect ADCR.

Example of setting 6CH in ADCR
CONTDATL
DAT
0CH
; CONTDATL is assigned to 0CH by using a symbol definition instruction.
CONTDATH
DAT
06H
; CONTDATH is assigned to 06H by using a symbol definition instruction.
