Table 1 Pin definitions
A 15-bit (P3.14 is missing) bidirectional I/O port. Port 3 is bit-
wise programmable for input or output via direction bits. For a
pin configured as input, the output driver is put into high-
impedance state. Port 3 outputs can be configured as push/
pull or open drain drivers. The following pins have alternate
functions:
P3.1
P3.2
