Arguments

Description

Writes the word value from the source address, or the value argument itself, into the destination 16-bit bank. If the source bank S is zero, the value given by V is written directly into the destination bank/address; otherwise, the value is retrieved from the source bank/address S/V, and then written to the destination bank/address D/A. If the destination is a 8-bit bank, only the low byte of the source will be written into it.
