    Figure 14-9 : Configuration of the connections between the microcontroller and XE1202A
    This documentation shows how to set-up the data transmission between the microcontroller and the XE1202A. For
    detailed information on the XE1202A functionality, external components, serial interface protocol and register set-
    up, please refer to the XE1202A datasheet.
    14.12.2.2 Microcontroller clock source derived from XE1202A crystal oscillator
    The XE1202A has a programmable output clock derived from the 39MHz crystal oscillator. This clock can be
    routed to the external clock input of the microcontroller (see Figure 14-9 and the clock block documentation). In this
    case, a precise clock derived from the XE1202A can be used to run the microcontroller in stead of the internal RC
    oscillator. The advantage is that the crystal oscillator is much more precise than the internal RC but the overall
    power consumption of the system will be somewhat larger.
    To enable the external clock output of the XE1202A, set the bit RTParam_Clkout=1 and use the bits
    ADParam_Clkfreq[1:0] to select the frequency between 9.75MHz and 1.22MHz (see XE1202A datasheet for
    details).
    To select the external clock in the microcontroller, set the bit EnExtClk = 1 in the register RegSysClk. Be aware
    that the external clock is divided by 2 at the input (see the clock block documentation for more details).
