Access:
Address:
• BA[9:0]: Base Address
Bits [31:30] are set by hardware, so the base address can only be in the memory space 0x40000000-0x7FFFFFFF. The
other bits contain the highest bits of the base address. If the page size is larger than 1 Mbyte, the unused bits of the base
address are ignored by the AMC decoder.
• CSEN: Chip Select Enable
0: Chip select is disabled.
1: Chip select is enabled.
• BAT: Byte Access Type
0: Byte write access type.
1: Byte select access type.
• TDF[2:0]: Data Float Output Time
These bits select the number of cycles added after a memory transfer.
