Digital I/O
There are up to five 8-bit I/O ports implemented: ports P1 through P5.
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt conditions is possible.
• Programmable pullup or pulldown on all ports.
• Programmable drive strength on all ports.
• Edge-selectable interrupt and LPM3.5 and LPM4.5 wake-up input capability is available for all the eight bits of
ports P1 and P2.
• Read and write access to port-control registers is supported by all instructions.
• Ports can be accessed byte-wise (P1 through P5) or word-wise in pairs (PA and PB).
Port Mapping Controller
The port mapping controller allows the flexible and re-configurable mapping of digital functions to port pins of
ports P1 through P3.

USCI_A0 UART RXD (Direction controlled by USCI - input)

USCI_A0 SPI slave in master out (direction controlled by USCI)
USCI_A0 clock input/output (direction controlled by USCI)

USCI_B0 SPI slave out master in (direction controlled by USCI)
USCI_B0 I2C clock (open drain and direction controlled by USCI)
(1) Input or output function is selected by the corresponding setting in the port direction register PxDIR.
(2) UART or SPI functionality is determined by the selected USCI mode.
(3) UCA0CLK function takes precedence over UCB0STE function. If the mapped pin is required as UCA0CLK input or output, USCI_B0 is
forced to 3-wire SPI mode even if 4-wire mode is selected.
(4) SPI or I2C functionality is determined by the selected USCI mode. If I2C functionality is selected, the output of the mapped pin drives
only the logical 0 to V_SS level.
