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.

DVSS
(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 will
be 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. In case the I2C functionality is selected the output of the mapped pin
drives only the logical 0 to V
SS
level.
(5)
UCB0CLK function takes precedence over UCA0STE function. If the mapped pin is required as UCB0CLK input or output USCI_A0 will
be forced to 3-wire SPI mode even if 4-wire mode is selected.
