The jump to the set address can be performed at any time once the required 64 cycles
have passed following the start of read address setup.
Read and write address setup can be performed asynchronously.

After the start of read or write jump address setup, if RAS or WAS respectively is returned
to the high level at an arbitrary bit position, the address bits input thereafter are masked,
and the corresponding bits retain their previous values.
