Inventory, used to perform the anticollision sequence.
Stay quiet, used to put the M24LR16E-R in quiet mode, where it does not respond to
any inventory command.
Select, used to select the M24LR16E-R. After this command, the M24LR16E-R
processes all Read/Write commands with Select_flag set.
Reset to ready, used to put the M24LR16E-R in the ready state.
Read block, used to output the 32 bits of the selected block and its locking status.
Write block, used to write the 32-bit value in the selected block, provided that it is not
locked.
Read multiple blocks, used to read the selected blocks and send back their value.
Write AFI, used to write the 8-bit value in the AFI register.
Lock AFI, used to lock the AFI register.
Write DSFID, used to write the 8-bit value in the DSFID register.
Lock DSFID, used to lock the DSFID register.
Get system info, used to provide the system information value
Get multiple block security status, used to send the security status of the selected
block.
Initiate, used to trigger the tag response to the Inventory initiated sequence.
Inventory initiated, used to perform the anticollision sequence triggered by the Initiate
command.
Write-sector password, used to write the 32 bits of the selected password.
Lock-sector, used to write the sector security status bits of the selected sector.
Present-sector password, enables the user to present a password to unprotect the
user blocks linked to this password.
Fast initiate, used to trigger the tag response to the Inventory initiated sequence.
Fast inventory initiated, used to perform the anticollision sequence triggered by the
Initiate command.
Fast read single block, used to output the 32 bits of the selected block and its locking
status.
Fast read multiple blocks, used to read the selected blocks and send back their value.
ReadCfg, used to read the 8-bit Configuration byte and send back its value.
WriteEHCfg, used to write the energy harvesting configuration bits into the
Configuration byte.
WriteDOCfg, used to write the RF WIP/BUSY pin configuration bit into the
Configuration byte.
SetRstEHEn, used to set or reset the EH_enable bit into the volatile Control register.
CheckEHEn, used to send back the value of the volatile Control register.
