Table 25.2 Specifying Break Data Register
Notes: 1. Specify an operand size when including the value of the data bus in the break condition.
25.2.7
BDMRB is a 32-bit readable/writable register. BDMRB specifies bits masked in the break data
specified by BDRB.
Notes: 1. Specify an operand size when including the value of the data bus in the break condition.
