Block and PDA Sector Locking Registers
SST49LF00xC 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.
SST49LF00xC also provides PDA Sector Locking Regis-
ters at addresses shown in Table 15. These locking regis-
ters can be accessed only after Open Protected Area
command is executed. After Hide Protected Area com-
mand, as well as after Power On and Reset, read from
addresses specified in Table 15 returns unused register
space data 00H, and write to these addresses is ignored.
In case of multi-byte read of any locking register, the device
will return register data for the addressed register until the
command finishes, or is aborted.
