8.2.3.3
The Guard Time Registers (GTR1, GTR2 and GTR3) are used for storing the number of guard ETU given by the card
during ATR. In transmission mode, the UART will wait this number of ETU before transmitting the character stored in
register UTR.
When register GTRx = FF:
Table 22 Registers GTR1, GTR2 and GTR3 (address 05H; read and write); note 1
Note
1. Register value at reset: all bits are cleared after reset.
