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 16.1,
Register Addresses (Address Order).
Table 4.1
4.1.2
ABRKSR consists of the address break interrupt flag and the address break interrupt enable bit.

Description
Address Break Interrupt Flag
[Setting condition]
When the condition set in ABRKCR is satisfied
[Clearing condition]
When 0 is written after ABIF=1 is read
Address Break Interrupt Enable
When this bit is 1, an address break interrupt request is
enabled.
Reserved
These bits are always read as 1.
