ADD is Super FX instruction that performs an addition. The source register is always an addend. The other addend may be any of the 16 R registers or an immediate value. The sum is stored in the destination register.
Unlike with ADC, CY is not an addend.
The source and destination registers should be specified in advance using WITH, FROM, or TO. Otherwise, R0 serves as the default.
Syntax
ADD Rn ADD #n
