9.3.1
The first 3 lines of Port 2 (P2.2..P2.0) serve as Fast External Interrupt inputs
(EX2IN...EX0IN) while P2.0 and P2.1 serve also as Serial Data Strobe outputs . The
remaining port lines can be used as GPI/O or to multiplex the connected LED field.
Table 9-1 summarizes the alternate functions of Port 2.
