I/O

P1.3 — Port 1 bit 3.

I/O

CEX0 — Capture/compare external I/O for PCA Module 0. Each

capture/compare module connects to a Port 1 pin for external

I/O. When not used by the PCA, this pin can handle standard I/O.

P2.0 to P2.7

I/O with

internal

pull-up

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 (IIL) because of 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. Port 2

also receives some control signals and a partial of high-order

address bits during the external host mode programming and

veriﬁcation.
