The manual says "In some cards if the Application contains a subroutine ClaInsFilter(), this subroutine is called whenever a command is received, before the BasicCard operating system looks for a match for CLA and INS."

For example if I send a card instruction like:


GET STATE
CLA=C0
INS=00
P1=00
P2=00
Le=00

The subrutine ClaInsFilter(), will be executed first before searching for the GET STATE function on the RTOS or will only execute the GET STATE function ?
