Pin Assignments
Figure 9 and Figure 10 identify all signals for the 56-pin
NX2LP-Flex package.
Three modes of operation are available for the NX2LP-Flex:
Port mode, GPIF Master mode, and Slave FIFO mode. These
modes define the signals on the right edge of each column in
Figure 9. The right-most column details the signal functionality

from the default NAND firmware image, which actually utilizes
GPIF Master mode. The signals on the left edge of the ‘Port’
column are common to all modes of the NX2LP-Flex. The
8051 selects the interface mode using the IFCONFIG[1:0]
register bits. Port mode is the power-on default configuration.
Figure 10 details the pinout of the 56-pin package and lists pin
names for all modes of operation. Pin names with an asterisk
(*) feature programmable polarity.
