TMP90C400/401
3.5 Function of Ports
The TMP90C400 contains a total of 56 pins (TMP90C401:
38-pins) input/output ports. These ports function not only for
the general-purpose I/O but also for the input/output of the
internal CPU and I/O. Table 3.5 describes the functions of
these ports.

These port pins function as the general-purpose input/
output ports by resetting. The port pins, for which input or out-
put is programmably selectable, function as input ports by reset-
ting. A separate program is required to use them for an internal
function.
The TMP90C401 functions in the same way as the
TMP90C400 except:
Port 0 always functions as Address/data bus (AD0 to AD7).
Port 1 always functions as Address bus (A8 to A15).
P26 and P27 of port 2 always function as RD and WR pins,
respectively.
