4.3. Other Commands
The Abort Command can be used to interrupt a Poll Single, Poll Continuous, or TX Data operation that is in progress.
If a Poll Continuous Command is sent but there is no card in the field, then an Abort Command is used to interrupt
the infinite polling loop. All other commands will timeout if no response is received, so it is usually not necessary to
use the Abort Command to interrupt them.
The Clear Command is used to clear the configuration registers and place AT88RF1354 in a known initial state. The
Clear Command is usually the first command sent after the reader is powered on and reset.
The Read Buffer Command and Write Buffer Command can be used to read and write the SRAM buffer that is used
to store RF commands and RF responses. These commands are never required to be used during normal operation
of the AT88RF1354. However, these commands are helpful for testing the integrity of the serial communications
channel during system development.
