8.11 I/O ports
The P89LPC906 has between 3 and 6 I/O pins: P0.4, P0.5, P0.6, P1.5, P3.0, and
P3.1 The exact number of I/O pins available depends on the clock and reset options
chosen, as shown in
Table 11
.
[1]
Required for operation above 12 MHz.
The P89LPC907 and P89LPC908 devices have either 5 or 6 I/O pins depending on
the reset pin option chosen.
8.11.1
Port configurations
All but one I/O port pin on the P89LPC906/907/908 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.
