• Short name: MINUS2
• Long name: Subtraction (16-bit)

Memory layout

0x88	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 SWord 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 16-bit range. If the Source Bank is 0 then the “Oper” is subtracted from 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.
