Set User Zone Command [$c1]
The Set User Zone command selects the user memory area to be addressed by the Read User Zone and Write User
Zone commands.
Before reading and writing data to the user memory, the host must select a User Zone with this command. Only one
User Zone may be selected at a time. At the time the zone is selected the host also chooses whether anti-tearing is
active for the selected zone. If anti-tearing is activated, then all writes to the User Zone will utilize anti-tearing until a
new Set User Zone command is received. Only PICCs in the Active State are permitted to answer this command.
