FI_DI_RATIO[7:0]
This register can only be written if write protection is disabled in the “Write Protect Mode Register” (WPMR.WPEN is zero).
• FI_DI_RATIO: FI Over DI Ratio Value
0: If ISO7816 mode is selected, the baud rate generator does not generate a signal.
1 - 2047: If ISO7816 mode is selected, the baud rate is the clock provided on CLK divided by FI_DI_RATIO.
