START
0000b
I
On the rising edge of CLK with LFRAME Low, the contents
of LAD0-LAD3 must be 0000b to indicate the start of a
LPC cycle.
21
CYCTYPE
+ DIR
0100b
I
Indicates the type of cycle and selects 1-byte reading. Bits
3:2 must be 01b. Bit 1 indicates the direction of transfer: 0b
for read. Bit 0 is Don’t Care.
3-10
8
ADDR
XXXX
I
A 32-bit address is transferred, with the most significant
nibble first. A23-A31 must be set to 1. A22=1 for memory
access, and A22=0 for register access. Table 5. shows the
appropriate values for A21-A20.

TAR
1111b
I
The host drives LAD0-LAD3 to 1111b to indicate a
turnaround cycle.

O
The LPC Flash Memory takes control of LAD0-LAD3
during this cycle.

WSYNC
0101b
O
The LPC Flash Memory drives LAD0-LAD3 to 0101b
(short wait-sync) for two clock cycles, indicating that the
data is not yet available. Two wait-states are always
included.

RSYNC
0000b
O
The LPC Flash Memory drives LAD0-LAD3 to 0000b,
indicating that data will be available during the next clock
cycle.
16-17

DATA
XXXX
O
Data transfer is two CLK cycles, starting with the least
significant nibble.
