Instruction Set
The Bit Manipulation Instructions allow:
– set bit
– clear bit
– complement bit
– jump if bit is set
– jump if bit is not set
– jump if bit is set and clear bit
– move bit from / to carry
Addressable bits, or their complements, may be logically AND-ed or OR-ed with the contents of the
carry flag. The result is returned to the carry register.
9.2 Introduction to the Instruction Set
The instruction set is divided into four functional groups:
– data transfer
– arithmetic
– logic
– control transfer
9.2.1 Data Transfer
Data operations are divided into three classes:
– general-purpose
– accumulator-specific
– address-object
None of these operations affects the PSW flag settings except a POP or MOV directly to the PSW.
