Buses
The NX2LP-Flex features an 8- or 16-bit ‘FIFO’ bidirectional data bus, multiplexed on I/O ports B and D.
The default firmware image implements an 8-bit data bus in GPIF master mode. It is recommended that additional interfaces added
to the default firmware image use this 8-bit data bus.
Enumeration
During the startup sequence, internal logic checks for the presence of NAND Flash with valid firmware. If valid firmware is found, the
NX2LP-Flex loads it and operates according to the firmware. If no NAND Flash is detected, or if no valid firmware is found, the
NX2LP-Flex uses the default values from internal ROM space for manufacturing mode operation. The two modes of operation are
described in the section Normal Operation Mode on page 7 and Manufacturing Mode on page 7.
