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.

1
CYCTYPE
+ DIR
011Xb
I
Indicates the type of cycle. Bits 3:2 must be
01b. Bit 1 indicates the direction of transfer: 1b
for write. Bit 0 is don’t care (X).
3-10

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.
11-12

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

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

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

SYNC
0000b
O
The LPC Flash Memory drives LAD0-LAD3 to
0000b, indicating it has received data or a
command.

TAR
1111b
(float)
N/A
The LPC Flash Memory floats its outputs and
the host takes control of LAD0-LAD3.
