FWH CYCLE DEFINITION
FIELD
NO. OF
CLOCKS
DESCRIPTION
START
1
"1101b" indicates FWH Memory Read cycle; while "1110b" indicates FWH
Memory Write cycle.
IDSEL
1
This one clock field indicates which FWH component is being selected.
MSIZE
1
Memory Size. There is always show “0000b” for single byte access.
TAR
2
Turned Around Time
ADDR
7
Address Phase for Memory Cycle. FWH supports the 28 bits address
protocol. The addresses transfer most significant nibble first and least
significant nibble last. (i.e. Address[27:24] on FWH[3:0] first , and
Address[3:0] on FWH[3:0] last.)
SYNC
N
Synchronous to add wait state. "0000b" means Ready, "0101b" means
Short Wait, "0110b" means Long Wait, "1001b" for DMA only, "1010b"
means error, and other values are reserved.
DATA
2
Data Phase for Memory Cycle. The data transfer least significant nibble first
and most significant nibble last. (i.e. DQ[3:0] on FWH[3:0] first , then
DQ[7:4] on FWH[3:0] last.)
