Ground Name
Description
PLLA_GND(1)
PLLP_GND(1)
PLL Ground—The PLL ground should be provided with an extremely low-impedance path to
ground. The user must provide adequate external decoupling capacitors.
PLLD_GND(1)
PLL Ground—The PLL ground should be provided with an extremely low-impedance path to
ground. The user must provide adequate external decoupling capacitors.
CORE_GND (4) Core Ground—The Core ground should be provided with an extremely low-impedance path to
ground. This connection must be tied externally to all other chip ground connections. The user must
provide adequate external decoupling capacitors.
IO_GND (5)
SHI, ESAI, ESAI_1, DAX and Timer I/O Ground—IO_GND is an isolated ground for the SHI, ESAI,
ESAI_1, DAX and Timer I/O. This connection must be tied externally to all other chip ground
connections. The user must provide adequate external decoupling capacitors.

Signal Description
EXTAL
Input
External Clock Input—An external clock source must be connected to EXTAL in
order to supply the clock to the internal clock generator and PLL.
This input is 5 V tolerant.
PINIT/NMI
Input
PLL Initial/Nonmaskable Interrupt—During assertion of RESET, the value of
PINIT/NMI is written into the PLL Enable (PEN) bit of the PLL control register,
determining whether the PLL is enabled or disabled. After RESET de assertion
and during normal instruction processing, the PINIT/NMI Schmitt-trigger input is
a negative-edge-triggered nonmaskable interrupt (NMI) request internally
synchronized to internal system clock.
Internal Pull up resistor.
This input is 5 V tolerant.
