Description
Input/Output Port 3 (P3.4). Port 3 is a bidirectional port with internal pull-up resistors.
Port 3 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 3 pins being pulled
externally low sources current because of the internal pull-up resistors.
Timer/Counter 0 Input (T0).
PWM Clock Input (PWMC).
PWM0 Voltage Output (PWM0). PWM outputs can be configured to uses
Port 2.6 and Port 2.7, or Port 3.4 and Port 3.3.
Input for External Clock Signal (EXTCLK). This pin must be enabled via the CFG832
register.
Input/Output Port 3 (P3.5). Port 3 is a bidirectional port with internal pull-up resistors.
Port 3 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 3 pins being pulled
externally low sources current because of the internal pull-up resistors.
Timer/Counter 1 Input (T1).
Active Low Convert Start Logic Input for the ADC Block When the External Convert
Start Function is Enabled (CONVST). A low-to-high transition on this input puts the
track-and-hold into its hold mode and starts conversion.
Input/Output Port 3 (P3.6). Port 3 is a bidirectional port with internal pull-up resistors.
Port 3 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 3 pins being pulled
externally low sources current because of the internal pull-up resistors.
Write Control Signal, Logic Output (WR). Latches the data byte from Port 0 into the
external data memory.
Input/Output Port 3 (P3.7). Port 3 is a bidirectional port with internal pull-up resistors.
Port 3 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 3 pins being pulled
externally low sources current because of the internal pull-up resistors.
Read Control Signal, Logic Output (RD). Enables the external data memory to Port 0.
Serial Clock Pin for I
User Selectable, I
SPI Master Output/Slave Input Data I/O Pin for SPI Interface (MOSI).
Input/Output Port 2 (P2.0). Port 2 is a bidirectional port with internal pull-up resistors.
Port 2 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 2 pins being pulled
externally low sources current because of the internal pull-up resistors.
External Memory Addresses (A8/A16). Port 2 emits the high order address bytes
during fetches from external program memory and middle and high order address
bytes during accesses to the external 24-bit external data memory space.
Input/Output Port 2 (P2.1). Port 2 is a bidirectional port with internal pull-up resistors.
Port 2 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 2 pins being pulled
externally low sources current because of the internal pull-up resistors.
External Memory Addresses (A9/A17). Port 2 emits the high order address bytes
during fetches from external program memory and middle and high order address
bytes during accesses to the external 24-bit external data memory space.
Input/Output Port 2 (P2.2). Port 2 is a bidirectional port with internal pull-up resistors.
Port 2 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 2 pins being pulled
externally low sources current because of the internal pull-up resistors.
External Memory Addresses (A10/A18). Port 2 emits the high order address bytes
during fetches from external program memory and middle and high order address
bytes during accesses to the external 24-bit external data memory space.
Input/Output Port 2 (P2.3). Port 2 is a bidirectional port with internal pull-up resistors.
Port 2 pins that have 1s written to them are pulled high by the internal pull-up
resistors, and in that state can be used as inputs. As inputs, Port 2 pins being pulled
externally low sources current because of the internal pull-up resistors.
External Memory Addresses (A11/A19). Port 2 emits the high order address bytes
during fetches from external program memory and middle and high order address
bytes during accesses to the external 24-bit external data memory space.
Input to the Inverting Oscillator Amplifier.
