UQPTM1/DQPTM1 control the Write access from the respective
transfer registers to the internal tables on a per-bit selection basis.
The mask registers correspond to the respective transfer registers
(UQPT1T1/UQPT2T1, DQPT1T1/DQPT2T1):
0
The dedicated bit of the transfer register overwrites the
table entry during Write.
Does not affect Read access.
