This register provides the data value when the error pin is configured as a general
purpose output.

pin0:
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.

pin2:
This bit acts as the general purpose output for the Error[2] pin. Software
sets/clears this bit to assert/deassert Error[2] pin. This bit applies only when
ERRPINCTL[5:4] = 01; otherwise it is reserved.
0: Assert ERR#[2] pin (drive low)
1: Deassert ERR#[2] pin (float high)
1: Deassert ERR#[2] pin (float high)
