Notes:
1. External weak pull-down resistor is required.
2. The reset state of these signals will be zero only if the reset state of the PCMCIA power source is zero. All of these pins are
required to be pulled up to the PCMCIA power source externally.
All inputs that have VCC clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
