3.2.5. Connection example for a 16-bit data bus
Figure 3-7 shows the connection of a 16-bit CPU to the TPS-1. The connection uses a 16-bit data bus and an address bus of 16 bit. Thus, it is possible
to access the entire address space of 64 KByte. Address line A0 should not be connected using the 16-bit data bus. The Address line LBU_A0_IN
should be connected to a pull down.
