8.13 I/O ports
The P89LPC904 has either 5 or 6 I/O pins depending on the reset pin option chosen.
Refer to
Table 6
.
8.13.1
Port configurations
All but one I/O port pin on the P89LPC904 may be configured by software to one of
four types on a bit-by-bit basis. These are: quasi-bidirectional (standard 80C51 port
outputs), push-pull, open drain, and input-only. Two configuration registers for each
port select the output type for each port pin.
P1.5 (RST) can only be an input and cannot be configured.
