LFRAME# must be active (low) for the part to respond.
Only the last start field (before LFRAME# transitions
high) should be recognized.

cycle. Bit 1 indicates the type of transfer “0” for Read. Bit 0 is
reserved.

ADDRESS
YYYY
IN
Address Phase for Memory Cycle. LPC protocol sup-
ports a 32-bit address phase. YYYY is one nibble of the
entire address. Addresses are transferred most-signifi-
cant nibble fist. See Table 3 for address bits definition
and Table 4 for valid memory address range.
