8.2 Operating Mode Selection - LPC Mode
Operation modes in LPC interface mode are determined by "START Cycle" when it is selected. When it
is not selected, its outputs (LAD[3:0]) will be disable. Please reference to the "LPC Cycle Definition".
8.3 LPC Cycle Definition
FIELD
NO. OF
CLOCKS

DESCRIPTION
Start
"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.)
