I develop a firmware with MPC5674F, and have a new question about the EBI.
in muxed 32-bit mode(MPC5674FRM Table29-3),the address bus which is latched can be 32-bit? Or ,the available address is only 24-bit,and the A[0:7] is always 0b00000000 for ever ?
Hi, it can be 32-bit.
Pay attention to section 3 in following document:
My board has two LVTH16373 to latch 32-bit Addresses.
But ,the A[0:7] is always 0b00000000,and the other 24-bit Addresses are OK . The SIU.PCR of D_ADD_DAT[0:15] are the same. I want to use the upper 8 address,what can I do ?
Can you explain MPC5674FRM Page 29-4. With this NOTE, if Addr can be 32-bit , I think the A[0:7] should be 0b001X_XXXX,because the range is from 0x2000_0000 to 0x3FFF_FFFF.
Do you have set D16_31 bit?
Yes,I set it.
The EBI.MCR = 0x0000_0806 .
