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.

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).

ADDR
XXXX
I
A 32-bit address phase is transferred starting with the most
significant nibble first. A23-A31 must be set to 1. A22 = 1 for
Array, A22 = 0 for registers access. For A20-A21 values, see
Table 3.
