23.3.1
A D/A data register, DADR, is internally a 10-bit register that holds data to be D/A converted.
When analog output is enabled, the value held by DADR is converted and output on the analog-
output pins. In the memory map, each DADR is configured of two registers, DADRnH and
DADRnL (n = 0, 1).
The eight higher-order bits of the corresponding DADR are stored in DADR0H or DADR1H.
DADR0H and DADR1H are directly readable and writable registers.
The two lower-order bits of the DADR are stored in DADR0L or DADR1L. DADR0L and
DADR1L are non-readable registers. Writing is accomplished by transferring values from the
temporary register, DADR01T.
When the value in a DADR is to be updated, the new lower-order two bits of the value must
previously have been written to DADR01T. The corresponding DADR is actually updated at the
same time as a new value is written to DADR0H or DADR1H. The eight higher-order bits are
reflected as written in DADR0H or DADR1H, while the two lower-order bits are updated by
transfer from DADR01T to DADR0L or DADR1L.
23.3.2
DADR0H and DADR1H are 8-bit readable/writable registers. When a value is written to
DADR0H or DADR1H, the corresponding bits of DADR01T are simultaneously transferred to
DADR0L or DADR1L.
