Port 2: Port 2 is an 8-bit bidirectional I/O port with internal
pull-ups. Port 2 pins are pulled HIGH by the internal pull-ups
when ‘1’s are written to them and can be used as inputs in this
state. As inputs, Port 2 pins that are externally pulled LOW will
source current (I
sends the high-order address byte during fetches from external
program memory and during accesses to external Data
Memory that use 16-bit address (MOVX@DPTR). In this
application, it uses strong internal pull-ups when making the
transition to ‘1’s.
P2[0] — Port 2 bit 0.
A8 — Address bit 8.
P2[1] — Port 2 bit 1.
A9 — Address bit 9.
P2[2] — Port 2 bit 2.
A10 — Address bit 10.
P2[3] — Port 2 bit 3.
A11 — Address bit 11.
P2[4] — Port 2 bit 4.
A12 — Address bit 12.
P2[5] — Port 2 bit 5.
A13 — Address bit 13.
P2[6] — Port 2 bit 6.
A14 — Address bit 14.
P2[7] — Port 2 bit 7.
A15 — Address bit 15.
Port 3: Port 3 is an 8-bit bidirectional I/O port with internal
pull-ups. Port 3 pins are pulled HIGH by the internal pull-ups
when ‘1’s are written to them and can be used as inputs in this
state. As inputs, Port 3 pins that are externally pulled LOW will
