Section 23 D/A Converter
23.3.3
Registers DADR0L and DADR1L are for storing the two lower-order bits of the ten-bit value for
D/A conversion held by the corresponding DADR. DADR0L and DADR1L are non-readable
registers. Writing is accomplished by transferring values from the temporary register, DADR01T.
When writing proceeds, the value must have been set beforehand in DADR01T.
Transfer from DADR01T to DADR0L proceeds when a value is written to DADR0H.
Transfer from DADR01T to DADR1L proceeds when a value is written to DADR1H.
23.3.4
DADR01T is an 8-bit temporary register that is used to transfer data to DADR0L and DADR1L.
Writing is only valid for bits 7 and 6. Values written to bits 5 to 0 are ignored. In reading, the most
recent setting (of bits 7 and 6) and the values for the two lower-order bits held in DADR0L and
DADR1L can be read. The value for the two lower-order bits of DADR1 can be read in bits 5 and
4. The value for the two lower-order bits of DADR0 can be read in bits 3 and 2.
Bits 1 and 0 are reserved. In reading, these bits are read as 1.
Bits 7 and 6 of DADR01T are used to store the two lower-order bits of a 10-bit value for D/A
conversion.
