Description
On the rising edge of CLK with LFRAME# Low, the contents of
LAD[3:0] indicate the start of an FWH cycle.
Indicates which FWH peripheral is selected. The value on the
LAD[3:0] is compared to the IDSEL strapping on the FWH device
pins to select which device is being addressed.
Note: From Intel(
(determined by ID strapping Pins ID[3:0]) of 0. It is advisable that
subsequent devices use incremental numbering.
A 28-bit address phase is transferred starting with the most signifi-
cant nibble first.
Always 0000b (single byte transfer).
Data transfer is two cycles, starting with least significant nibble.
The LPC host drives LAD[3:0] to 1111b to indicate a turnaround
cycle.
The FWH device takes control of LAD[3:0] during this cycle.
The FWH device drives LAD[3:0] to 0000b to indicate it has
received data or a command.
The FWH device drives LAD[3:0] to 1111b, indicating a turnaround
cycle.
The FWH device floats its output and the LPC host takes control of
LAD[3:0].
