Integrated I/O (IIO) Configuration Registers
14.8.23 ERRPINCTL
This register provides the option to configure an error pin to either as a special purpose
error pin which is asserted based on the detected error severity, or as a general
purpose output which is asserted based on the value in the ERRPINDAT. The assertion
of the error pins can also be completely disabled by this register.
14.8.24 ERRPINSTS
This register reflects the state of the error pin assertion. The status bit of the
corresponding error pin is set upon the deassertion to assertion transition of the error
pin. This bit is cleared by the software with writing 1 to the corresponding bit.

pin2:
This bit is set upon the transition of deassertion to assertion of the Error pin.
Software write 1 to clear the status. Hardware will only set this bit when the
corresponding ERRPINCTL field is set to 10b.
