Description
P1[7] — Port 1 bit 7.
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
the internal pull-ups. Port 2 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 transitioning 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 source current (I
the internal pull-ups.
P3[0] — Port 3 bit 0.
RXD — Serial input port.
P3[1] — Port 3 bit 1.
TXD — Serial output port.
P3[2] — Port 3 bit 2.
INT0 — External interrupt 0 input.
P3[3] — Port 3 bit 3.
INT1 — External interrupt 1 input
P3[4] — Port 3 bit 4.
T0 — External count input to Timer/Counter 0.
