  • Opcode: 0x18
  • Short name: IFUW
  • Long name: If (Unsigned Word)

Memory layout

0x18 B1 / B2 A V C E

Arguments

  • const Bit[4] B1: First memory bank to access.
  • const Bit[4] B2: Second memory bank to access.
  • const UShort A: Address, from the first bank, of the value to retrieve.
  • const UShort V: Unsigned value to compare the retrieved value to, or address from the second bank of the value to retrieve, if B2 is non-zero.
  • const UByte C: Type of comparison to perform.
  • const UByte E: Amount to jump if the comparison does not hold.

Description

This is similar to the IFUB opcode, but it allows the value to be larger than 0xFF.
