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

BRCLR tests all bits selected by the immediate mask.
If all selected 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.
MASK8 specifies a 16-bit immediate value where
either the upper or lower 8 bits contains all zeros.
AA specifies a 7-bit PC relative offset.
X:aa represents a 6-bit absolute address. Refer to
Absolute Short Address (Direct Addressing): <aa>
on page 4-22.
X:<<pp represents a 6-bit absolute I/O address. Refer
to I/O Short Address (Direct Addressing): <pp> on
page 4-23.
