The hexadecimal value stored in the Programmable
Divider Register (PDR) is the auto-reload value of an 8-bit
counter clocked by the card clock (CLK); when the value is
loaded in the counter, it counts from this value till overflow;
then it is reloaded with the same value and the count
restarts. The output of the counter is then divided by
31 or 32 depending on the programmed value of the
UART prescaler. The result is the ISO 7816 UART CLK
which is used for shifting the data in or out on the I/O line.
The example shown in Fig.7 shows how to program a
division factor of 372. With these registers, the baud rates
given in Table 7 are achieved according to ISO 7816.
The division ratio of 31 or 32 depends on which prescaler
is selected, and the hexadecimal value is the value
programmed within the PDR.

Note
1. A division factor of F4H, for example, would be 1111 0100 reading from D7 to D0.
