Description
Direct Address (JP, CALL)
In a JP or CALL operand, DA is a 16-bit Program Memory address in the range
of 0000H to FFFFH . DA replaces the contents of the Program Counter for
execution to continue at a new location in Program Memory. In assembly
source, the address is represented as a label.
Relative Address (JR, DJNZ)
RA is a signed 8-bit Program Memory offset in the range +127 to –128, relative
to the address of the next instruction in Program Memory. In a JR or DJNZ
operation, RA is added to the program counter to cause execution to continue
at a new location in Program Memory. In assembly source, the jump address is
represented as an absolute label, and the assembler calculates RA.
