BFCLR tests all bits selected by the 16-bit immediate
mask. If all selected bits are set, then the C bit is set. Oth-
erwise it is cleared. Then it clears all selected bits.
All registers in DDDDD are permitted except HWS.
X:aa represents a 6-bit absolute address. Refer to Abso-
lute 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.
