Assignment of a value is indicated by the symbol “←”. For example,
dst ← dst + src
indicates the source data is added to the destination data and the result is
stored in the destination location.
The notation 'addr(n)' is used to refer to bit'n' of a given location. For
example,
dst (7)
refers to bit 7 of the destination operand.
Assembly Language Syntax
For proper instruction execution, Z8 assembly language syntax requires
‘dst, src’ be specified, in that order. The following instruction descriptions
show the format of the object code produced by the assembler. This
binary format should be followed by users who prefer manual program
coding or who intend to implement their own assembler.
Example: If the contents of registers 43h and 08h are added and the
result is stored in 43h, the assembly syntax and resulting object code is:
