  • Opcode: 0x86
  • Short name: PLUS2
  • Long name: Addition (16-bit)

Memory layout

0x77 D/S Dest Oper

Arguments

  • const Bit[4] D: Destination bank
  • const Bit[4] S: Source bank
  • const UByte Dest: The destination variable, to which the operand is added.
  • const SWord Oper: The operand, added to the destination.

Description

Adds two numbers together and stores the result back into “Dest”. The result of the addition wraps around into the 16-bit range. If the Source Bank is 0 then the “Oper” is added to the destination value. If the Source Bank is an 16 bit bank, then the “Oper” is the address in that bank where the operand is.
