I/O
Port 2
is a an 8-bit quasi-bidirectional I/O port with internal pullup
resistors. Port 2 pins that have a 1 written to them are pulled
high by the internal pullup resistors, and in that state can be
used as inputs. As inputs, port 2 pins being externally pulled
low will source current (
I
IL
, in the DC characteristics)
because of the internal pullup resistors. Port 2 emits the
high-order address byte during fetches from external
program memory and during accesses to external data
memory that use 16-bit addresses (MOVX @DPTR). In this
application it uses strong internal pullup transistors when
issuing 1s. During accesses to external data memory that
use 8-bit addresses (MOVX @Ri), port 2 issues the
contents of the P2 special function register and uses only
the internal pullup resistors.

I/O
Port 0
is an 8-bit open-drain bidirectional I/O port. Port 0 pins that
have a 1 written to them float, and in that state can be used
as high-impendance inputs. Port 0 is also the multiplexed
low-order address and data bus during accesses to external
program or data memory. In this application it uses strong
internal pullup transistors when issuing 1s.
