1 EMI I/O interface power supply should be set up according to external memory. For example, if using SDRAM then

NVCC_EMI1,2,3 should all be set at 3.3 V (typ.). If using MDDR or DDR2, NVC_EMI1,2,3 must be set at 1.8 V (typ.).

2 MLB Interface I/O pins can be programmed to function as GPIO for the consumer and industrial parts by setting NVCC_MLB

to 1.8 or 3.3 V. NVCC_MLB can be left floating.

3 The Fusebox read supply is connected to supply of the full speed USB PHY. FUSE_VDD is only used for programming. It is

recommended that FUSE_VDD be connected to ground when not being used for programming.
