The POR circuit monitors V
until the device has completed its flash memory configuration of the SRAM logic. The
weak pull-up resistor (R) from the I/O pin to V
keep the I/O pins from floating. The 3.3-V tolerance control circuit permits the I/O
pins to be driven by 3.3 V before V
I/O pins from driving out when the device is not fully powered or operational. The
hot socket circuit prevents I/O pins from internally powering V
driven by external signals before the device is powered.
