A.2. AHB-Lite master

An AHB-Lite master has the same signal interface as a full AHB bus master, except that it does not support HBUSREQx and HGRANTx.

The Lock functionality is still required because the master might be performing a transfer to a multi-port slave. The slave must be given an indication that no other transfer should occur to the slave when the master requires locked access.

An AHB-Lite master is not required to support either the SPLIT or RETRY response and only the OKAY and ERROR responses are required, so the AHB-Lite master interface does not require the HRESP[1] input.
