  • Opcode: 0x87
  • Short name: MINUS
  • Long name: Subtraction (8-bit)

Memory layout

0x87 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 subtracted.
  • const UByte Oper: The operand to be subtracted from the destination.

Description

Subtracts two numbers and stores the result back into “Dest”. The result of the subtraction wraps around into the range of 0-255. If the Source Bank is 0 then the “Oper” is subtracted from the destination value. If the Source Bank is an 8 bit bank, then the “Oper” is the address in that bank where the operand is.
