Clock Range is not available in Pulse Generator mode. If the Clock Source is either
Internal or External 10 MHz Reference in the Pulse Generator mode, the internal
clock range and vector rate are determined automatically according to the
user-defined frequency. For details, refer to the Table 1-21.
If the frequency is just at a boundary in the table below, the settings in the higher
range of the hardware clock frequencies are applied.
