I/O
Name and Functions
Port 0:
Port 0 is an 8-bit open drain bi-directional I/O port. As an output port each pin can
sink several LS TTL inputs. Port 0 pins float that have ‘1’s written to them, and in this state
can be used as high-impedance inputs. Port 0 is also the multiplexed low-order address and
data bus during accesses to external memory. In this application, it uses strong internal pull-
ups when transitioning to V
OH.
Port 0 also receives the code bytes during the external host
mode programming, and outputs the code bytes during the external host mode verification.
External pull-ups are required during program verification.
Port 1:
Port 1 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 1 output buff-
ers can drive LS TTL inputs. Port 1 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 1 pins that are
externally pulled low will source current because of the internal pull-ups. P1[5, 6, 7] have
high current drive of 16 mA. Port 1 also receives the low-order address bytes during the
external host mode programming and verification.
T2:
External count input to Timer/Counter 2 or Clock-out from Timer/Counter 2
T2EX:
Timer/Counter 2 capture/reload trigger and direction control
ECI:
PCA Timer/Counter External Input:
This signal is the external clock input for the PCA timer/counter.
CEX0:
Compare/Capture Module External I/O
Each compare/capture module connects to a Port 1 pin for external I/O. When not used by
the PCA, this pin can handle standard I/O.

Port 2:
Port 2 is an 8-bit bi-directional 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 because of the
internal pull-ups. Port 2 sends the high-order address byte during fetches from external Pro-
gram 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
V
OH
. Port 2 also receives some control signals and a partial of high-order address bits dur-
ing the external host mode programming and verification.
Port 3:
Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. The Port 3 output buff-
ers can drive LS TTL inputs. 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 because of the internal pull-ups. Port 3 also
receives some control signals and a partial of high-order address bits during the external
host mode programming and verification.
