BGT Block Guard Time Value
The value in this register is the block guard time. Time from START bit of last byte sent from the EMV SIM
module to the START bit of the first byte sent from the SmartCard must be greater than this value. If it is
not, then the BGT flag will be set.

GPCNT0 General Purpose Counter 0 Timeout Value
The value written to this register will be used to compare to the general purpose counter 0 in the EMV SIM
module. Once the General purpose counter reaches this value, the GPCNT0 flag in the TX_STATUS
register will be set. This counter is intended to be used for any events that must be monitored for duration
based on the card clock, receiver sample rate, or ETU rate (transmit clock). Example: ATR arrival time and
ATR duration.
