For each pin in the table, each line in the Function column is a separate function of the pin. For all I/O pins the selection of primary pin function or secondary function or

GPIO is done in the SIU except where explicitly noted. See the Signal details table for a description of each signal.

The P/A/G column indicates the position a signal occupies in the muxing order for a pin—Primary, Alternate 1, Alternate 2, Alternate 3, or GPIO. Signals are selected by

setting the PA field value in the appropriate PCR register in the SIU module. The PA field values are as follows: P - 0b0001, A1 - 0b0010, A2 - 0b0100, A3 - 0b1000, or G -

0b0000. Depending on the register, the PA field size can vary in length. For PA fields having fewer than four bits, remove the appropriate number of leading zeroes from

these values.

The Pad Configuration Register (PCR) PA field is used by software to select pin function.

Values in the PCR No. column refer to registers in the System Integration Unit (SIU). The actual register name is “SIU_PCR” suffixed by the PCR number. For example,

PCR[190] refers to the SIU register named SIU_PCR190.

The VDDE and VDDEH supply inputs are broken into segments. Each segment of slow I/O pins (VDDEH) may have a separate supply in the 3.3 V to 5.0 V range (-

10%/+5%). Each segment of fast I/O (VDDE) may have a separate supply in the 1.8 V to 3.3 V range (+/- 10%).

See Table 5 for details on pad types.
