Sets (1) the contents of bit j (bit specified by the value j in the immediate field) of M(DP).
Clears (0) the contents of bit j (bit specified by the value j in the immediate field) of M(DP).
Skips the next instruction when the contents of bit j (bit specified by the value j in the immediate field)
of M(DP) is “0.”
Skips the next instruction when the contents of register A is equal to the contents of M(DP).
Skips the next instruction when the contents of register A is equal to the value n in the immediate field.
Branch within a page : Branches to address a in the identical page.
Branch out of a page : Branches to address a in page p.
Branch within a page : Branches to address (a6 a5 a4 A3 A2 A1 A0) determined by replacing the low-
order 4 bits of the address a in the identical page with register A.
Branch out of a page : Branches to address (a6 a5 a4 A3 A2 A1 A0) determined by replacing the low-
