The Z16C30 contains 13 pins per channel for channel I/O, 16 pins for address and data, 12
pins for CPU handshake, and 14 pins for power and ground.
Three separate bus interface types are available for the device. The Bus Configuration
Register (BCR) and external connections to the AD bus control selection of the bus type.
A 16-bit bus is selected by setting BCR bit 2 to a 1. The 8-bit bus is selected by setting
BCR bit 2 to 0 and tying AD15–AD8 to V
