parasitic capacitance, package and board, must be calculated in order to reach 17.5 pF (minimum targeted load for the
oscillator) by taking into account the internal load C
tance must be: 17.5 pF - 4 pF = 13.5 pF which means that 27 pF is the target value (27 pF from xin to gnd and 27 pF from
xout to gnd). If 20 pF load is targeted, the sum of pad, package, board and external capacitances must be 20 pF - 4 pF = 16
pF which means 32 pF (32 pF from xin to gnd and 32 pF from xout to gnd).

The master clock is the maximum clock at which the system is able to run. It is given by the
smallest value of the internal bus clock and EBI clock.
