4 2 BFCHG tests all bits selected by the 16-bit
immediate mask. If all selected bits are set,
6 2
then the C bit is set. Otherwise it is cleared.
Then it inverts all selected bits.
6 2
All registers in DDDDD are permitted except
4 2
HWS.
X:aa represents a 6-bit absolute address.
4 2
Refer to Absolute Short Address (Direct
Addressing): <aa> on page 4-22
6 3
X:pp represents a 6-bit absolute I/O address.
4 2 BFCLR tests all bits selected by the 16-bit
immediate mask. If all selected bits are set,
6 2
then the C bit is set. Otherwise it is cleared.
Then it clears all selected bits.

X:pp represents a 6-bit absolute I/O address.
4 2 BFSET tests all bits selected by the 16-bit
immediate mask. If all selected bits are clear,
6 2
then the C bit is set. Otherwise it is cleared.
Then it sets all selected bits.

10/8 2 BRCLR tests all bits selected by the immediate
mask. If all selected bits are clear, then the carry
12/10 2
bit is set and a PC relative branch occurs. Other-
12/10 2
wise it is cleared and no branch occurs.
10/8 2
All registers in DDDDD are permitted except
10/8 2
HWS.
12/10 3
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.
X:pp represents a 6-bit absolute I/O address.
