Have a great day,
128Mbyte Nor flash (64M x 16) has 25 address inputs A[0:24], where A0 is the least significant (lsb). The MPC8379 eLBC in Non-Multiplexed mode can support only (32M x 16) because in this mode only 24 lsb of the 31-bit address of 16-bit word can be provided on the LA pins. Hence you need use Multiplexed mode i.e. to use external latch controlled by LALE outputs and latch address from LAD[6:26] pins. The latch outputs need to be connected to the 21 most significant of the NOR flash address inputs (A[24:4]):
8379->latch--NOR
LAD[6] ->LBA[6]---A24
LAD[7] ->LBA[7]---A23
…
LAD[26] ->LBA[7]---A4
The rest addr. inputs A[4:0] can be connected to the non-multiplexed LA[27:30] outputs
8379 --NOR
LA27—A3
LA28—A2
LA29—A1
LA30—A0
16 – bit data are provided on the LAD[0:15] (LAD0 is msb) so recommended connection is
8379 –NOR
LAD[0]—D15
LAD[1]—D14
…
LAD[15]—D0
Control signals connection is straightforward
LWE to the NOR WE
LOE to the NOR OE
Any one of LCSn to the NOR CE
You can get explanation how to connect NOR Flash in the app. note AN3665 “PowerQUICC Design Checklist. For PowerQUICC II Pro (MPC837x) Devices” You can download it from the Freescale page
