... The Z86E73/E74 devices offer a one-time programmable (OTP) option. For applications demanding powerful I/O capabilities, the Z86E73/L73's dedicated input and output lines are grouped into four ports, and into seven ports for the Z86E74/L74. They are configurable under software control to provide timing, status signals, or parallel I/O ...
