Dear all,
For my project, I am connecting my reader to a MCU which act as the host. The card uses T1 protocol and we need to consider the CWT and BWT. Therefore for this case, the CWT and BWT actually indicate the waiting time for the command to transfer from the MCUàCard or Reader àCard?
Is it true that BWT and CWT for T=1 protocol and work waiting time for T=0 protocol only in used for command that deal with the card? Other command that only deal with the reader like Open Reader command, Close Reader command and Set Reader Parameter command that only deal with the reader will not use the CWT and BWT?
At the beginning, before my reader can deal with the card, I need to sent out a startup command to open the operation of the reader where it is done under default reader condition where it uses T=0 protocol. So, the command is only sent from the MCU à Reader where it does not deal with the card. Therefore, do we still need to consider the waiting time (CWT=WI*960 for T=0 Protocol) when we are receiving the response for the startup command (that mean each byte of the response must be receive by MCU
within the CWT), since the waiting time only in used when we deal with the card?
Thanks for helping!
