28V input conditions. These should also be tested with part configured for 5V input configuration, i.e., VIN = VCC5 = PVCC = 5V.
the input voltage is 5V, VCC5 pin will be used as a 5V input, the internal LDO regulator is disabled and the VIN must be connected to the VCC5.
In both cases the PVCC pin should always be connected to VCC5 pin (refer to “Pin Descriptions” on page 10 for more details).
