6.2 Signal Descriptions

Table 6-1 lists the pins by function and describes that function.

Note:

All IO pins of the device (except NERROR IN, NERROR_OUT, and WARM_RESET) are non-failsafe; hence, care needs to be taken that they are not driven externally without the VIO supply being present to the device.
