TMS320F28379D: FLASH Bank sectors

Karthick Kumar T K

Part Number: TMS320F28379D
Hi, I'm facing difficulty in understanding the flash bank and sector organization. Help me in clarifying the below questions. thank you.
1.What is the maximum no. of bits that the flash reads at once ?
 2.I found in Types.h that, there are 7 flash banks and 64 sectors whereas in the datasheet, but it is mentioned as there's bank0 for cpu1 and bank1 for cpu2 so only 2 flash banks each of size 256KW. Also as shown below there's 14 sectors as mentioned in the datasheet. Can you clarify about the extra banks and sectors defined in Types.h.

    The flash will read 128 bits at a time(4 32-bit words, 32-bit is the fetch size for each C28x CPU instruction fetch)

    The datasheet is correct for both banks and sectors.  The Type.h enumerations reflect the maximum supported banks/sectors for this flash technology, but all may not be used on a given device.

    Best,
