XYEC and XYSC in BBRC as shown below. BDMRCH and BDMRCL are initialized to H'0000
by a power-on reset; after a manual reset, their values are undefined.
BDMRC Configuration
XYEC = 0
XYEC = 1
Bits 31 to 0:
BDMCn
0
1
Notes: 1. n = 31 to 0

2. When including the data bus value in the break condition, specify the operand size.
3. When specifying byte size, and using odd-address data as a break condition, set the
value in bits 7 to 0 of BDRC and BDMRC. When using even-address data as a break
condition, set the value in bits 15 to 8. The unused 8 bits of these registers have no
effect on the break condition.
