Miscellaneous Pins
BOOT_SEL
[2:0]
IC
Boot select pins.
(input)
Indicates type of boot device.
Input
Input
PWR_EN
OC
Power Enable for the power supply.
(output) When
negated, it signals the power supply to remove power to
the core because the system is entering sleep mode.
Driven High
Driven low while
entering sleep
mode. Driven high
when sleep exit
sequence begins.
nBATT_FAULT
IC
Main Battery Fault.
(input) Signals that main battery is
low or removed. Assertion causes PXA255 processor
processor to enter sleep mode or force an imprecise data
exception, which cannot be masked. PXA255 processor
will not recognize a wake-up event while this signal is
asserted. Minimum assertion time for nBATT_FAULT is 1
ms.
Input
Input
nVDD_FAULT
IC
VDD Fault.
(input) Signals that the main power source is
going out of regulation. nVDD_FAULT causes the
PXA255 processor to enter sleep mode or force an
imprecise data exception, which cannot be masked.
nVDD_FAULT is ignored after a wake-up event until the
power supply timer completes (approximately 10 ms).
Minimum assertion time for nVDD_FAULT is 1 ms.
Input
Input
nRESET
IC
Hard reset.
(input) Level -sensitive input used to start the
processor from a known address. Assertion terminates
the current instruction abnormally and causes a reset.
When nRESET is driven high, the processor starts
execution from address 0. nRESET must remain low until
the power supply is stable and the internal 3.6864 MHz
oscillator has stabilized.
Input
Input. Driving low
during sleep will
cause normal
reset sequence
and exit from sleep
mode.
