87 / 154 page  November 6, 2013 S25FS-S_00_04 S25FS-S Family 87 Da ta Shee t (Prelim i nar y ) 10.1 Command Set Summary 10.1.1 Extended Addressing To accommodate addressing above 128 Mb, there are two options: 1. Instructions that always require a 4-byte address, used to access up to 32 Gb of memory: 2. A 4-byte address mode for backward compatibility to the 3-byte address instructions. The standard 3-byte instructions can be used in conjunction with a 4-byte address mode controlled by the Address Length configuration bit (CR2V[7]). The default value of CR2V[7] is loaded from CR2NV[7] (following power-up, hardware reset, or software reset), to enable default 3-byte (24-bit) or 4-byte (32-bit) addressing. When the address length (CR2V[7]) set to 1, the legacy commands are changed to require 4-bytes (32-bits) for the address field. The following instructions can be used in conjunction with the 4-byte address mode configuration to switch from 3 bytes to 4 bytes of address field.
