LCD Segment-Driver Output; LCD Common Drive Output. These pins function as LCD
segment or common drive outputs. Configuring a pin as a common drive output disables the
segment function for that pin.
LCD Common Drive 0, Output. This pin functions as a LCD common-drive output.
Digital I/O, Type D Port 5.0; Timer B0 Pin B; Serial Port 0 Receive; External Edge-Selectable
Interrupt 8. This pin defaults to an input with a weak pullup after reset and functions as
general-purpose I/O. The port pad contains a Schmitt voltage input and can be configured as
an external interrupt. Enabling a special function disables the pin as digital I/O.
Digital I/O, Type D Port 5.1; Timer B0 Pin A; Serial Port 0 Transmit; External Edge-
Selectable Interrupt 9. This pin defaults to an input with a weak pullup after reset and
functions as general-purpose I/O. The port pad contains a Schmitt voltage input and can be
configured as an external interrupt. Enabling a special function disables the pin as general-
purpose I/O.
Digital I/O, Type-D Port 5.2; External Edge-Selectable Interrupt 10; RTC Square-Wave Output.
This pin defaults to an input with a weak pullup after reset and functions as general-purpose
I/O. The port pad contains a Schmitt voltage input and can be configured as an external
interrupt. Enabling a special function disables the pin as general-purpose I/O.
Digital I/O, Type D Port 5.3; External Edge-Selectable Interrupt 11; Active-Low SPI Slave-
Select Input. This pin defaults to an input with a weak pullup after reset and functions as
general-purpose I/O. The port pad contains a Schmitt voltage input and can be configured as
an external interrupt. Enabling a special function disables the pin as general-purpose I/O.
Digital I/O, Type D Port 5.4; External Edge-Selectable Interrupt 12; SPI Master Out-Slave In.
This pin defaults to an input with a weak pullup after reset and functions as general-purpose
I/O. The port pad contains a Schmitt voltage input and can be configured as an external
interrupt. Enabling a special function disables the pin as general-purpose I/O.
Digital I/O, Type D Port 5.5; External Edge-Selectable Interrupt 13; SPI Clock Output. This pin
defaults as an input with a weak pullup after a reset and functions as general-purpose I/O. The
port pad contains a Schmitt input circuitry and can be configured as an external interrupt.
Enabling a special function disables the pin as general-purpose I/O.
Digital I/O, Type D Port 5.6; External Edge-Selectable Interrupt 14; SPI Master In-Slave Out.
This pin defaults to an input with a weak pullup after reset and functions as general-purpose
I/O. The port pad contains a Schmitt voltage input and can be configured as an external
interrupt. Enabling a special function disables the pin as general-purpose I/O.
Digital I/O, Type D Port 6.0; External Edge-Selectable Interrupt 15; JTAG Test Clock Input.
This pin defaults to an input with a weak pullup after reset and functions as general-purpose
I/O. The port pad contains a Schmitt voltage input and can be configured as an external
interrupt. Enabling a special function disables the pin as general-purpose I/O.
Digital I/O, Type D Port 6.1; External Edge-Selectable Interrupt 16; JTAG Test Data Input.
This pin defaults to an input with a weak pullup after reset and functions as general-purpose
I/O. The port pad contains a Schmitt voltage input and can be configured as an external
interrupt. Enabling a special function disables the pin as general-purpose I/O.
