I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k
IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)
§For the C6415T and C6416T devices, these pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
The C6414T device does
not
support the PCI or UTOPIA peripherals; therefore, these muxed peripheral pins are standalone peripheral functions
for this device.
