Section 6 User Break Controller (UBC)
6.2.15
BDRDH
BDRDL
Break data register D (BDRD) consists of two 16-bit readable/writable registers: break data
register DH (BDRDH) and break data register DL (BDRDL). BDRDH specifies the upper half
(bits 31 to 16) of the data used as a channel D break condition, and BDRDL specifies the lower
half (bits 15 to 0). The data bus connected to the X/Y memory can also be specified as a break
condition by making a setting in the XYED bit/XYSD bit in break bus cycle register D (BBRD).
When XYED = 1, the upper 16 bits (BDD31 to BDD16) of BDRD specify the X data bus, and the
lower 16 bits (BDD15 to BDD0) specify the Y data bus.
