Table 4-28. PRCM Signal Descriptions
DESCRIPTION
Device Clock output 1. Can be used externally for devices with non-
critical timing requirements, or for debug, or as a reference clock on
GPMC as described in Table 5-44 GPMC/NOR Flash Interface
Switching Characteristics - Synchronous Mode - Default and Table 5-
46 GPMC/NOR Flash Interface Switching Characteristics -
Synchronous Mode - Alternate.
Device Clock output 2. Can be used externally for devices with non-
critical timing requirements, or for debug.
Device Clock output 3. Can be used xternally for devices with non-
critical timing requirements, or for debug.
Power on Reset (active low). This pin must be asserted low until all
device supplies are valid (see reset sequence/requirements)
Device Reset Input
Reset out (Active low). This pin asserts low in response to any global
reset condition on the device.⁽²⁾
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.
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
System Oscillator OSC0 Crystal output
Auxiliary Oscillator OSC1 Crystal output
External Reference Clock 0. For Audio and other Peripherals.
External Reference Clock 1. For Audio and other Peripherals.
External Reference Clock 2. For Audio and other Peripherals.
External Reference Clock 3. For Audio and other Peripherals.
RMII Reference Clock (50MHz). This pin is an input when external
reference is used or output when internal reference is used.
