Operating Modes table). Like the Byte Write instruction, it is followed by an address byte and a data byte, but in this case the contents are all “Don't
Care” (refer to the Setting the Write Protection figure). Another difference is that the voltage, V

write-protection cannot be cleared by any instruction, or by power-cycling the device. Also, once the PSWP instruction has been successfully
executed, the TSE2002B3C no longer acknowledges any instruction (with a Device Type Identifier of 0110) to access the write-protection settings.
The TSE2002B3C has three software write-protection features, allowing the bottom half of the memory area (addresses 0x00 to 0x7F) to be
Software write-protection is handled by three instructions:
SWP: Set Write Protection
CWP: Clear Write Protection
PSWP: Permanently Set Write Protection
The level of write-protection (set or cleared) that has been defined using these instructions, remains defined even after a power cycle.
If the software write-protection has been set with the SWP instruction, it can be cleared again with a CWP instruction.
The two instructions (SWP and CWP) have the same format as a Byte Write instruction, but with a different Device Type Identifier (refer to the I
If the software write-protection has been set with the PSWP instruction, the first 128 bytes of the memory are permanently write-protected. This
