Break data mask register D (BDMRD) consists of two 16-bit readable/writable registers: break
data mask register DH (BDMRDH) and break data mask register DL (BDMRDL). BDMRDH
specifies which bits of the break data set in BDRDH are to be masked, and BDMRDL specifies
which bits of the break data set in BDRDL are to be masked. Operation also depends on bits
