Function
(<bit 7> of <Rd>)
Converts byte data in a general register to word data by
extending the sign bit.
0
Converts byte data in a general register to word data by
padding with zero bits.
(EAd) – 0
Compares general register or memory contents with 0.
0 – (EAd)
Obtains the two’s complement of general register or
memory contents.
0
Clears general register or memory contents to 0.
(EAd) — 0, (1)
Tests general register or memory contents, then sets the
most significant bit (bit 7) to “1.”
Function
Rd (EAs)
