R/W Break Data Mask B
Specifies bits masked in the break data of channel B
specified by BDRB (BDB31 to BDB0).
0: Break data BDBn of channel B is included in the
break condition
1: Break data BDBn of channel B is masked and is not
included in the break condition
Note: n = 31 to 0
Notes: 1. Specify an operand size when including the value of the data bus in the break condition.
2. When the byte size is selected as a break condition, the same byte data must be set in
bits 15 to 8 and 7 to 0 in BDMRB as the break mask data in BDRB.
