As long the EPC bank is not write locked standard EPC READ/WRITE commands can be used to modify the flags. Table 11. ChangeConfig custom command Command RFU Data RN CRC-16 No. of bits 16 8 16 16 16 Description 11100000 00000111 00000000 Toggle bits XOR RN16 handle - The bits to be toggled in the configuration register need to be set to '1'. E.g., sending 0000 0000 0000 0000 1001 XOR RN16 will activate the EPC Read Protect and PSF bit. Sending the very same command a second time will disable the features. The reply of the ChangeConfig will return the current register setting. Table 12. ChangeConfig custom response table Starting state Condition Response Next state ready all - ready arbitrate, reply, acknowledged all - arbitrate valid handle, Status word needs to change Backscatter unchanged StatusWord immediately open open valid handle, Status word does not need to change Backscatter StatusWord immediately open valid handle, Status word needs to change Backscatter modified StatusWord, when done secured valid handle, Status word does not need to change Backscatter StatusWord immediately secured secured invalid handle - secured |
