Operation
BRCLR
1.The first cycle count refers to the case when the condition is true and the branch is taken. The
second cycle count refers to the case when the condition is false and the branch is not taken.

BRCLR tests all the targeted bits defined by
the immediate mask. If all the targeted bits
are clear, then the carry bit is set and a
PC-relative branch occurs. Otherwise it is
cleared and no branch occurs.
All registers in DDDDD are permitted except
HWS and Y.
MASK8 specifies a 16-bit immediate value,
where either the upper or lower 8 bits contain
all zeros. AA specifies a 7-bit PC-relative off-
set.
