BDRCH
BDRCL
Break data register C (BDRC) consists of two 16-bit readable/writable registers: break data
register CH (BDRCH) and break data register CL (BDRCL). BDRCH specifies the upper half
(bits 31 to 16) of the data used as a channel C break condition, and BDRCL 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 XYEC bit/XYSC bit in break bus cycle register C (BBRC).
When XYEC = 1, the upper 16 bits (BDC31 to BDC16) of BDRC specify the X data bus, and the
lower 16 bits (BDC15 to BDC0) specify the Y data bus.
