6.2 Pin List

The following tables provide the ATSAMA5D27-WLSOM1 module pin description.

Important: Compared to SAMA5D2 Series devices, some PIO features are not listed. These features are used internally on the ATSAMA5D27-WLSOM1 and cannot be shared with other PIOs for use with features or for signal integrity.

The device features several PIO controllers that multiplex the I/O lines of the peripheral set. The following PIOx Pin Description tables define how the I/O lines are multiplexed on the different PIO controllers. The "Reset State" column shows whether the PIO line resets in I/O mode or in Peripheral mode. If I/O is shown, the PIO line resets with the characteristics (input, output, pull-up or pull-down) indicated in this same column, so that the device is configured in a known state as soon as the reset is released. As a result, PIO_CFGR.FUNC resets to ‘0’. If a signal name is shown in the “Reset State” column, the PIO line is assigned to this function and PIO_CFGR.FUNC is not set to ‘0’. That is the case for pins controlling memories, in particular address lines, which require the pin to be driven as soon as the reset is released.
