ThingMagic M5e-Compact - Manual (Page 167)

Set Application Commands
Command Set 167
Note
Setting the parameters using Set Protocol Configuration will override the
implicit value set by a previous call to Set User Mode. Likewise, a
subsequent call to Set User Mode will override the parameters set by Set
Protocol Configuration. Get Protocol Configuration will always return the
current setting regardless of whether it was set by Set Protocol
Configuration or Set User Mode.
Note
Changing these protocol parameters manually using Set Protocol Configuration
(9Bh) will maintain their value across changes in the current protocol using
Set Current Tag Protocol (93h) . Their values will NOT be reset if the protocol is
reset, only if the module is power cycled or the application firmware is
reloaded by a
Start Bootloader (09h) followed by a Boot Firmware (04h) .
