TESTCLK
IC
Test Clock. This pin should be used for test purposes only. An end user should
ground this pin.
Power and Ground Pins
VCC
SUP
Positive supply for the applications processor internal Logic. Connect this supply
to the low voltage (.85 - 1.3v) supply on the PCB.
VSS
SUP
Ground supply for the applications processor internal logic. Connect these pins to
the common ground plane on the PCB.
PLL_VCC
SUP
Positive supply for the PLLs and Oscillators. It is recommended that you connect
this pin to the common low voltage supply.
PLL_VSS
SUP
Ground signal for PLLs.
VCCQ
SUP
Positive supply for all CMOS I/O, except memory bus and PCMCIA pins. Connect
these pins to the common 3.3 volt supply on the PCB.
VSSQ
SUP
Ground supply for all CMOS I/O except memory bus and PCMCIA pins. Connect
these pins to the common ground plane on the PCB.
VCCN
SUP
Positive supply for memory bus and PCMCIA pins. Connect these pins to the
common 3.3 volt supply on the PCB.
VSSN
SUP
Ground supply for memory bus and PCMCIA pins. Connect these pins to the
common ground plane on the PCB.
BATT_VCC
SUP
Backup battery connection. Connect this pin to the backup battery supply. If a
backup battery is not required, then this pin may be connected to the common
3.3 volt supply on the PCB.
NOTE:
1.
GPIO Reset Operation:
Configured as GPIO inputs by default after any reset. The input buffers for these
pins are disabled to prevent current drain.
