Description

XSPIaddress register

Fields

ADDRESS

Address Address to be sent to the external device. In HyperBus protocol, this field must be even as this protocol is 16-bit word oriented. In dual-memory configuration, AR[0] is forced to 0. Writes to this field are ignored when BUSY = 1 or when FMODE = 11 (memory-mapped mode). Some memory specifications consider that each address corresponds to a 16-bit value. XSPI considers that each address corresponds to an 8-bit value. So the software needs to multiple the address by two when accessing the memory registers.
