1 _{Alternate functions are chosen by setting the values of the PCR[PA] bitfields inside the SIUL module.}
PCR[PA] = 00 selects Option 0
PCR[PA] = 01 selects Option 1
PCR[PA] = 10 selects Option 2
PCR[PA] = 11 selects Option 3
This is intended to select the output functions. To use one of the input functions, the PCR[IBE] bit must be written to ‘1’, regardless of the values selected in
the PCR[PA] bitfields. For this reason, the value corresponding to an input only function is reported as “—”.
2 _{Special functions are enabled independently from the standard digital pin functions. Enabling standard I/O functions in the PCR registers may interfere with}
their functionality. ADC functions are enabled using the PCR[APC] bit; other functions are enabled by enabling the respective module.
3 _{Using the PSMI registers in the System Integration Unit Lite (SIUL), different pads can be multiplexed to the same peripheral input. Please see the SIUL chapter}
of the PXD20 Microcontroller Reference Manual for details.
4 _{See the “Pad types” section for an explanation of the letters in this column.}
5 _{Reset configuration is given as I/O direction and pull, e.g., “Input, pullup”.}
6 _{Out of reset pins PH[0:3] are available as JTAG pins (TCK, TDI, TDO and TMS respectively). It is up to the user to configure pins PH[0:3] when needed.}
