Figure 16. Count down example (binary format)
The counter with block address 6 controls the Reload command used to reset the resettable
OTP area (addresses 0 to 4). Bits b
of these 11 bits is updated, the SRI512 detects the change and adds an Erase cycle to the
Write_block command for locations 0 to 4 (see
Erase cycle remains active until a Power-off or a Select command is issued. The SRI512’s
resettable OTP area can be reloaded up to 2,047 times (2
