Block Locking Registers

SST49LF016C provides software controlled lock protection through a set of Block Locking registers.

The Block Locking Registers are read/write registers and they are accessible through standard

addressable memory locations specified in Table 14. Unused register locations will return 00H if read.

In case of multi-byte register reads with Firmware Memory cycle, the device will return register data for

the addressed register until the command finishes, or is aborted.

tem memory map depending on ID strapping values on ID[3:0] pins when multiple LPC memory devices are used in a

system.
