When configured as DSPI_D_PCS[0], the OBE bit should be set to one for master operation, and set to zero for
slave operation. When configured as GPO, the OBE bit should be set to one.
2
When configured as DSPI_D_PCS[0] in slave operation, the IBE bit should be set to one. When configured as PCS
in master operation or GPO, the IBE bit may be set to one to reflect the pin state in the corresponding GPDI register.
Setting the IBE bit to zero reduces power consumption. When configured as GPI, the IBE bit should be set to one.

In cases where an I/O function can be either an input or an output, I/O direction is specified using the IBE and OBE
bits. Set IBE = 1 for input or OBE = 1 for output.
2
For I/O functions that change direction dynamically, such as the external data bus, switching between input and
output is handled internally and the IBE and OBE bits are ignored.

When configured as DSPI_B_PCS[2], DSPI_C_SOUT or GPO, the IBE bit may be set to one to reflect the pin state
in the corresponding GPDI register. Setting the IBE bit to zero reduces power consumption. When configured as
GPI, the IBE bit should be set to one.
