View Full Version : XMC4500 I/O pin reset state, default configuration

Nov 18th, 2013, 12:49 AM

I have been searching for more than an hour now, and have trouble finding an overview of all the default states/levels for the I/O pins.
In the pin tables, there are Notes for 'non default configurations', but I cannot find the descriptions for the 'default configuration'.

I need to know the default level of I/O after a power-up or reset.

Hope someone can point me in the right direction.

Found it on page 25-9 ch 25.6 (thanks to Infineon Sweden!)

All Port registers are reset with the System Reset (see Reset Control chapter in the
System Control Unit). The standard reset values are defined such that the port pins are
configured as tri-state inputs, output driver disabled and no pull devices active.
