operate as a depth of one. This is the default/reset behavior of the module and can be
adjusted using the PFIFO[RXFE] and PFIFO[TXFE] bits. Individual watermark levels
are also provided for transmit and receive.
There are multiple ways to ensure that a data block (set of characters) has completed
transmission. These methods include:
44.8.2 ISO-7816 initialization sequence
This section outlines how to program the UART for ISO-7816 operation. Elements such
as procedures to power up or power down the smartcard, and when to take those actions,
are beyond the scope of this description. To setup the UART for ISO-7816 operation:

baud rate generator. Remember that the baud rate generator is disabled when the
baud rate is zero. Writing to the BDH has no effect without also writing to BDL.
According to the 7816 specification the initial (default) baud rating setting should be
Fi = 372 and Di = 1 and a maximum frequency of 5 MHz. In other words the BDH,
BDL and C4 registers should be programmed such that the transmission frequency
should be 1/372th of the clock provided to the smartcard device and should not
exceed 5 MHz.

MODEM[TXRTSE] = 0, and MODEM[TXCTSE] = 0.
