7.2 Operating Mode Selection - LPC Mode
Operation modes in LPC interface mode are determined by "cycle type" when it is selected. When it
is not selected, its outputs (LAD[3:0]) will be disable. Please reference to the "Standard LPC Memory
Cycle Definition".

DESCRIPTION
Start
1
"0000b" appears on LPC bus to indicate the initial
Cycle Type &
Dir
1
"010Xb" indicates memory read cycle; while "011xb" indicates memory
write cycle. "X" mean don't have to care.
TAR
2
Turned Around Time
Addr.
8
Address Phase for Memory Cycle. LPC supports the 32 bits address
protocol. The addresses transfer most significant nibble first and least
significant nibble last. (i.e. Address[31:28] on LAD[3:0] first , and
Address[3:0] on LAD[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, 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 LAD[3:0] first ,
then DQ[7:4] on LAD[3:0] last.)
