Product specification
USB smart card reader (OTP or ROM)
TDA8030; TDA8031
8.1.5.3
Baud rate selection using F and D; card clock frequency f
CLK
= 3.58 MHz for PSC = 31 and 4.92 MHz for
PSC = 32 (31;12 means prescaler set to 31 and PDR set to 12)
8.1.5.4
Guard time register
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.

Guard time register (address 05H; read and write); note 1
Note
1.
All bits are cleared after reset.
8.1.5.5
UART configuration register 1
The UART Configuration Register 1 (UCR1) is used for setting the parameters of the ISO UART.
