I/O port 4
8-bit COMS I/O port.
Each bit can be set individually as either
input or output by the P4DIR register.
Pull-up resistor for each bit can be selected
individually by the P4PLU register.
At reset, the input mode (P42, P43, P46,
P47) is selected and pull-up resistor is dis-
abled.

Serial interface
transmission data
output pin
Transmission data output pins for serial
interface 0, 1, and 2.
Select output by the P1DIR and P2DIR regis-
ters and serial pin function by the P1MD and
P2MD registers.
These can be used as normal I/O pins when
serial interfaces are not used.
