Chapter 4 - BRI Commands Memory Bank 1 EPCID Memory For memory bank 1, if a non-zero ACCESS password has been written to a tag, you must specify an ACCESS password in the WRITE command in order to write to memory bank 1. Note that in memory bank 1, the data can always be read with a correct ACCESS password or without an ACCESS password. If the correct password is not given, the commands will return a PVERR indicating that an invalid password has been given.

Memory Bank 1 EPCID Memory
For memory bank 1, if a non-zero ACCESS password has been written to a tag, you
must specify an ACCESS password in the WRITE command in order to write to
memory bank 1. Note that in memory bank 1, the data can always be read with a
correct ACCESS password or without an ACCESS password. If the correct password
is not given, the commands will return a PVERR indicating that an invalid password
has been given.
The example below illustrates writing the ACCESS password first, then performing
the READ, WRITE, and PROTECT operations.
