Special care should be taken with any unused GPIO data bits.
An unused GPIO data bit, either a pin on the chip or a port bit
that is not bonded on a particular package, must not be left
floating when the device enters the suspend state. If a GPIO data
bit is left floating, the leakage current caused by the floating bit
may violate the suspend current limitation specified by the USB
specifications. If a ‘1’ is written to the unused data bit and the port
is configured with open drain outputs, the unused data bit
remains in an indeterminate state. Therefore, if an unused port
bit is programmed in open-drain mode, it must be written with a
‘0.’ Notice that the CY7C66013C always requires that P3[7:5] be
written with a ‘0.’ When the CY7C66113C is used the P3[7]
should be written with a ‘0.’

In normal non HAPI mode, reads from a GPIO port always return
the present state of the voltage at the pin, independent of the
settings in the Port Data Registers. If HAPI mode is activated for
a port, reads of that port return latched data as controlled by the
HAPI signals (see
During reset, all of the GPIO pins are set to a high impedance
input state (‘1’ in open drain mode). Writing a ‘0’ to a GPIO pin
drives the pin LOW. In this state, a ‘0’ is always read on that GPIO
pin unless an external source overdrives the internal pull down
device.
