Connect this pin to V
Switches the data bus in external memory space 3. The data
bus is 16 bits long when the this pin is held "L" and 8 bits long
when the this pin is held "H". Set it to either one.

Output CS0 to CS3 that are chip-select signals specifying an external space
Outputs WRL, WRH, (WR, BHE) and RD signals. WRL and WRH
can be switched with WR and BHE by program
If external data bus is 16 bits wide, data is writtenn to an even
address when WRL is held "L".
Data is written to an odd address when WRH is held "L".
Data is read when RD is held "L".
Data is written to external memory space when WR is held "L".
Data is read when RD is held "L".
An odd address is accessed when BHE is held "L".
Select WR, BHE and RD for an external 8-bit data bus
ALE is a signal latching address
The microcomputer is placed in a hold state while the HOLD pin
is held "L"
Outputs an "L" siganl while the microcomputer is placed in a hold state
Bus is placed in a wait state while the RDY pin is held "L"
