26.3.15 Data Register (DR)
DR is a register for reading/writing FIFO data.
Word/byte access is enabled to addresses of this register.
Initial value:
The following shows examples of DR access.
When data is written to DR in the following steps 1 to 4, the transmit data is stored in the FIFO as
shown in figure 26.2.
1. Write word data H'0123 to DR.
2. Write byte data H'45 to DR.
3. Write word data H'6789 to DR.
4. Write byte data H'AB to DR.
When the receive data is stored in the FIFO as shown in figure 26.2 (for example, after data is
started to be received while the FIFO is empty and data is received in the order of H'01, H'23, ...,
H'AB), data can be read from DR in the following steps 5 to 8.
5. Read byte data H'01 from DR.
6. Read word data H'2345 from DR.
7. Read byte data H'67 from DR.
8. Ready word data H'89AB from DR.

Description
Register for reading/writing FIFO data.
Word/byte access is enabled.
When DR is accessed in words, the upper and lower
bytes are transmitted or received in that order. Word
access and byte access can be done in random order.
However, (DR address + 1) cannot be accessed in
bytes.
