Introduction
devices to be used as primary or secondary non-volatile storage. The on-chip error correction code (ECC)
and parity checking circuitry of the NAND Flash controller frees the CPU for other tasks. WLAN,
Bluetooth and expansion options are provided through PCMCIA/CF, USB, and MMC/SD host controllers.
The device is packaged in a 289-pin MAPBGA.

System Control
OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET.
Logic level one is a voltage that corresponds to Boolean true (1) state.
Logic level zero is a voltage that corresponds to Boolean false (0) state.
To set a bit or bits means to establish logic level one.
To clear a bit or bits means to establish logic level zero.
A signal is an electronic construct whose state conveys or changes in state convey information.
A pin is an external physical connection. The same pin can be used to connect a number of signals.
Asserted means that a discrete signal is in active logic state.
— Active low signals change from logic level one to logic level zero.
— Active high signals change from logic level zero to logic level one.
Negated means that an asserted discrete signal changes logic state.
— Active low signals change from logic level zero to logic level one.
— Active high signals change from logic level one to logic level zero.
