The P89LPC9102/9103/9107 has either 6, 7, or 8 I/O pins depending on the reset pin
option and clock source option chosen. Refer to
All but one I/O port pin on the P89LPC9102/9103/9107 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.
