Pin No. Pin Description
55
General Purpose pin. In reset stage this pin defines chip operates in 16 or 32-bit mode.
Pull-down is for 32-bit mode and pull-up (by 4.7K) is for 16-bit mode. If this pin is
floating, it will be as default for 32-bit mode.
54
General Purpose pin. In reset stage this pin defines chip operates in little-endian or
big-endian mode. Pull-down is little-endian mode and pull-up is big-endian mode. If
this pin is floating, it will as default for little-endian mode.
52
Connect to ground for normal operation.
