Four basic address spaces support a wide range of mem- ory configurations. The designer has easy access to regis- ter mapped peripheral and I/O circuits. For applications demanding powerful I/O capabilities, the Z86E33/733/E34 have 24 pins and the Z86E43/743/E44 have 32 pins of dedicated input and output. These lines are grouped into four ports, eight lines per port, and are config- urable under software control to provide timing, status sig- nals, and parallel I/O with or without handshake, and ad- dress/data bus for interfacing external memory. Notes: All Signals with a preceding front slash, "/", are active Low, e.g., B//W (WORD is active Low); /B/W (BYTE is active Low, only).
