$80/9DAB WRAM-Clear-DMA

This Subroutine is half a setup for a DMA and starts the DMA. The first half of the setup has to be done before this Subroutine gets called. A call can be found at $80/801B. This is a fixed Transfer, so it's used for Clear Up DMAs. Furthermore, due to it's construction it is fixed to WRAM addresses. Before this subroutine is called, there are additional values that are loaded into certain registers:

A: Source Bank (8 bit)

X: Source Address (16 bit)

Y: Destination WRAM Address (16 bit)

Carry Bit Set: WRAM Bank $7F / Carry Bit Clear: WRAM Bank $7E
