8.1.5.3
8.1.5.4
The Guard Time Register (GTR) is used for storing the number of guard ETUs given by the card during ATR.
In transmission mode, the UART will wait this number of ETU + 0.5 before transmitting the character stored in UTR.
In T = 1 protocol, GTR = FFH means operation at 11.5 ETU. In T = 0 protocol and GTR = FFH means operation at
12.5 ETU.
Table 20 Guard time register (address 05H; read and write); note 1
Note
1. All bits are cleared after reset.
8.1.5.5
The UART Configuration Register 1 (UCR1) is used for setting the parameters of the ISO UART.
Table 21 UART configuration register 1 (address 06H; read and write); note 1
Note
1. All bits are cleared after reset.
