Indicate the time added for character protection after
transmitting a character to the smart card. The interval
between the start of two successive characters is 12 etus
(no addition) when the value of this register is H'00, is 13
etus when the value is H'01, and so on, up to 266 etus for
H'FE. If the value of this register is H'FF, the interval
between the start of two successive characters is 11 etus
in T = 1 mode and is 12 etus in T = 0 mode.
