Arguments
- const Bit[4] D: Destination bank.
- const Bit[4] S: Source bank.
- const UByte A: Destination address.
- const UByte V: Value to be written/Source address.
Description
Writes the byte value from the source address, or the value argument itself, into the destination 8-bit bank. If the source bank S is zero, the value given by V is written directly into the destination 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 16-bit bank, the high byte of the destination will remain unchanged.
