In order to use both functions SPI and QDU with an interface, we would like to switch the following pins parallel: 32 + 54, 100 + 53 and 99 + 55.
If the initial state can not be displayed or selected in the configuration tool, does the state then apply as described after a reset in the data sheet?
Hello,
There is a Note in Datasheet regarding I/O terminals status at reset and after reset is released.
Terminals are pulled down or high depending on the default function on each terminal. Once the system reset is released, the I/Os are controlled by the default states of the individual control registers.
For example, the GIODIRx register defaults to configuring all GIOx terminals as inputs (DIR = 0). In this case the value of the DOUT, DSET and DCLR registers do not affect the terminals. The pull select registers (PULSEL) define the pull applied to the terminals. In case of GIOx terminals, the pull-select registers default to applying a pull-down on the terminals.
