5.1.5. XCLK Feature
When precision sampling frequency is required, external clock mode can be activated by setting
XCLK
to Low. Under such condition, the resistor at Rosc pin must be removed and the external clock signal
must be applied to the Rosc pin. These conditions must be satisfied prior to any operations.
However, when internal clock is used,
XCLK
must be linked to High.
The external clock frequencies required for various sampling frequencies are listed in below table.

PERATION
The direct trigger is selected by the

pin. Once chosen, the supply voltage must be reset to
allow the device to construct itself to the appropriate configuration by re-defining the function on the
related control pins. Also, the mode change is only allowed while the device is in power down state and
inhibited during an operation is in progress.
