4.2 Pin Descriptions
The following table provides detailed pin descriptions for the RF; clock, reset, and JTAG; Bluetooth; SSI
and UART; and UART, SPI1, and TIM including the GPIO shared package pins.
In the following table, the general-purpose input/output (GPIO) is designed to share package pins with
other peripheral modules on the chip. If the peripheral, which normally controls a given pin, is not
required, then the pin may be programmed to be a general-purpose input/output (GPIO) or alternate
function 2 with programmable pull-up. The GPIO module design has two available ports (Port B and Port
C). The individual control for each pin can be in normal functional mode, alternate function mode 2, or
GPIO mode. The individual direction control for each pin is in GPIO mode. The individual pull-up enable
control for each pin is in normal function mode, alternate function mode 2, or GPIO mode.

Normal mode. The peripheral module controls the output enable and any output data to the pad and
any input data from the pad is passed to the peripheral.
Alternate function 1 mode (GPIO). The GPIO module controls the output enable to the pad and
supplies any data to be output.
Alternate function 2 mode. The peripheral module controls the output enable and any output data
to the pad and any input data from the pad is passed to the peripheral.
