SIGNAL NAME

DESCRIPTION

TYPE

BALL

rstoutn

Reset out (Active low). This pin asserts low in response to any global reset condition

on the device.

resetn

Device Reset

porz

Power on Reset (active low). This pin must be asserted low until all device supplies

are valid (see reset sequence/requirements).

xref_clk0

External Reference Clock 0. For Audio and other Peripherals.

xref_clk1

External Reference Clock 1. For Audio and other Peripherals.

C5, C6

xref_clk2

External Reference Clock 2. For Audio and other Peripherals.

H15

xi_osc0

System Oscillator OSC0 Crystal input / LVCMOS clock input. Functions as the input

connection to a crystal when the internal oscillator OSC0 is used. Functions as an

LVCMOS-compatible input clock when an external oscillator is used.

E16

xi_osc1

Auxiliary Oscillator OSC1 Crystal input / LVCMOS clock input. Functions as the

input connection to a crystal when the internal oscillator OSC1 is used. Functions as

an LVCMOS-compatible input clock when an external oscillator is used

C17

xo_osc0

System Oscillator OSC0 Crystal output

D16

xo_osc1

Auxiliary Oscillator OSC1 Crystal output

SIGNAL NAME

DESCRIPTION

TYPE

BALL

nmin

Non maskable interrupt input - active-low. This pin can be optionally routed to the

DSP NMI input or as generic input to the ARM cores.

sys_nirq1

External interrupt event to any device INTC

K17, L15

sys_nirq2

External interrupt event to any device INTC

K15, K16

esm_error

This signal indicates a severe device failure. For more information see Error

Signaling Module in the device TRM.
