Logical Instructions
The logical instructions perform the operations AND, OR, and XOR (Exclusive OR). Other logical operations can
be performed by combining these basic operations. For example, complementing is accomplished by
exclusiveORing the Accumulator with FF Hex.
Logical AND (AND)
Logical OR (OR)
Exclusive OR (XOR)
Accumulator Bit Manipulation Instructions
The Accumulator bit manipulation instructions allow the user to shift the Accumulator bits and to swap its two
nibbles.
Rotate Right Through Carry (RRC)
Rotate Left Through Carry (RLC)
Swap Nibbles of Accumulator (SWAP)
Stack Control Instructions
Push Data onto Stack (PUSH)
Pop Data off of Stack (POP)
Memory Bit Manipulation Instructions
The memory bit manipulation instructions allow the user to set and reset individual bits in memory.
Set Bit (SBIT)
Reset Bit (RBIT)
Reset Pending Bit (RPND)
Conditional Instructions
The conditional instruction test a condition. If the condition is true, the next instruction is executed in the normal
manner; if the condition is false, the next instruction is skipped.
If Equal (IFEQ)
If Not Equal (IFNE)
If Greater Than (IFGT)
If Carry (IFC)
If Not Carry (IFNC)
If Bit (IFBIT)
If B Pointer Not Equal (IFBNE)
And Skip if Zero (ANDSZ)
Decrement Register and Skip if Zero (DRSZ)
No-Operation Instruction
The no-operation instruction does nothing, except to occupy space in the program memory and time in
execution.
No-Operation (NOP)
