This register is used for setting the parameters of the ISO UART.

8.10.3.5
This register defines the clock to the card and the clock to the ISO UART. Note that if bit CKU in the prescaler register
of the selected card (register UCR2) is set, then the ISO UART is clocked at twice the frequency to the card, which allows
to reach baud rates not foreseen in ISO 7816 norm.

Not used.
Force Inverse Parity. If FIP = 1, then the UART will NAK a correct received character,
and will transmit characters with wrong parity bit.
Test bit. FC must be left to logic 0.
Protocol. If PROT = 1, then protocol type is asynchronous T = 1; if PROT = 0, the
protocol is T = 0.
Transmit/Receive. This bit is set by software for transmission mode. A change from
logic 0 to logic 1 will set bit TBE in register USR. T/R is automatically reset by hardware
if LCT has been used before transmitting the last character.
Last Character to Transmit. This bit is set by software before writing the last character
to be transmitted in register UTR. It allows automatic change to reception mode. It is
reset by hardware at the end of a successful transmission. When LCT is being reset, the
bit T/R is also reset and the ISO 7816 UART is ready for receiving a character.
Start Session. This bit is set by software before ATR for automatic convention detection
and early answer detection. It is automatically reset by hardware at 10.5 ETU after
reception of the initial character.
Convention. This bit is set if the convention is direct. Bit CONV is either automatically
written by hardware according to the convention detected during ATR, or by software if
bit AUTOCONV in register UCR2 is set.
