Table 1. Special Function Registers
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 inter-
faces added to the default firmware image use this 8-bit data
bus.

Enumeration
During the start-up 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
Mode” on page 5.
