7.2.7 Break Data Mask Register B (BDMRB)
BDMRB is a 32-bit read/write register. BDMRB specifies bits masked in the break data specified
by BDRB. A power-on reset initializes BDMRB to H'00000000.

Bits 31 to 0—Break Data Mask Register B31 to B0 (BDMB31 to BDMB0): Specifies bits in
the channel B break data bits specified by BDRB (BDB31—BDB0).
Bits 31 to 0:
BDMBn Description
0 Break data BDBn of channel B is included in the break condition (Initial value)
1 Break data BDBn of channel B is masked and is not included in the break
condition
n = 31 to 0
Notes: 1. Specify an operand size when including the value of the data bus in the break condition.
2. When a byte size is specified as a break condition, the same-byte data must be set in
bits 15 to 8 and bits 7 to 0 in BDRB for the break data.
