When the controller needs to transmit data to the card, it
first sets the bit UC3 in the UART CONFIGURATION
which configures the UART in the transmission mode.
As soon as a character has been written in the UART
TRANSMIT register, the UART makes the conversion,
calculates the parity and starts the transmission on the
rising edge of ENABLE. When the character has been
transmitted, it surveys the I/O line at 11 ETU in order to
know if an error has been detected by the card.
