TMS570LC4357: PortA and PortB flash memory access

Part Number: TMS570LC4357

Hello,

In Datasheet, it is mentionned there are two slave ports (Flash_PortA and Flash_PortB) to access to the flash memory.

To read in FPROM Bank0 and 1:

1- Which port is configured by default? Port A, PortB or  Both? if BOTH, how is it managed?

2- Is it necessary that Software configure the port Access? Which TMS registers must be used to configure it?

Best regards,

François

    Hello Francos,

    The L2FMC flash has 2 slave ports: PORT A and PORT B. The CPU will access the flash memory via the flash controller PORT A. The PORT B is used for other masters (DMA, FTU, etc).
