When an address break is set in the data read cycle or data write cycle, the data bus used will
depend on the combination of the byte/word access and address. Table 4.1 shows the access and
data bus used. When an I/O register space with an 8-bit data bus width is accessed in word size, a
byte access is generated twice. For details on data widths of each register, see section 21.1,
Register Addresses (Address Order).

Description
Data Compare Condition Select 1 and 0
These bits set the comparison condition between the data
set in BDR and the internal data bus.
00: No data comparison
01: Compares lower 8-bit data between BDRL and data
10: Compares upper 8-bit data between BDRH and data
