10.5.12 UART Fractional Divider Register
Table 174: UART IrDA Control Register (ICR - 0x4000 C024) bit description
The PulseDiv bits in ICR are used to select the pulse width when the fixed pulse width
mode is used in IrDA mode (IrDAEn = 1 and FixPulseEn = 1). The value of these bits
should be set so that the resulting pulse width is at least 1.63 µs.
possible pulse widths.
Table 175: IrDA Pulse Width
The UART Fractional Divider Register (FDR) controls the clock pre-scaler for the baud
rate generation and can be read and written at the user’s discretion. This pre-scaler takes
the APB clock and generates an output clock according to the specified fractional
requirements.
Important: If the fractional divider is active (DIVADDVAL > 0) and DLM = 0, the value of
the DLL register must be 3 or greater.
