4.6.1 G2BLKPERMALOCK_RD: Read USER Block Lock Status
4.6.2 G2BLKPERMALOCK_LK: Set USER Block Lock
G2BLKPERMALOCK_RD {blkpntr} {range}
Reads the block permalock status
Performs a Gen2 blockpermalock read instruction. The USER memory block lock status is read with
a granularity of 16 blocks encoded into a 16-bit data word. The blkpntr parameter defines the
starting block in units of 16 blocks – blkpntr=0 maps to block 0; blkpntr=1 maps to block 16;
blkpntr=2 maps to block 32, etc. The range parameter defines the number of 16-block permalock
status data words to return. Thus, the block permalock read status is further defined by:
G2BLKPERMALOCK_LK {blkpntr} {mask}
Performs the locking function of the block permalock Gen2 command
Performs a Gen2 blockpermalock lock instruction. Once a USER memory block has been
permalocked, it may not be unlocked and is permanent – the respective USER memory block may no
longer be written to. The blkpntr parameter defines the starting block in units of 16 blocks –
blkpntr=0 maps to block 0; blkpntr=1 maps to block 16; blkpntr=2 maps to block 32, etc. The mask
defines one or more discrete blocks are to be locked. The G2BLKPERMALOCK_LK command
supports only a single set of 16 consecutive blocks – as such, the range parameter is fixed at x01 (not
included in the CLI command). USER memory blocks that are to be locked are defined within the
mask parameter by asserting the respective bit to a logic one. For example, say the following blocks
are to be block-permalocked:
Two G2BLKPERMALOCK_LK commands would be required. The parameters for the first
command would be:
The parameters for the second command would be:
Parameter
blkpntr
range
blocklock_start_block = blkpntr
blocklock_end_block = blkpntr + (range×16)-1
Parameter
blkpntr
mask

blkpntr = 0
mask = b1011_0000_0000_0010 = xB002
blkpntr = 2
mask = b1000_0000_1000_0000 = x8080
