(1)

The I/O pin TSTPT_6 enables the ASIC to use two different oscillator frequencies through a pullup control at initial ASIC power-up.

TSTPT_6 should be grounded so that 24 MHz is always selected.

(2)

The frequency accuracy for MOSC is ±200 PPM. This includes impact to accuracy due to aging, temperature, and trim sensitivity. The

MOSC input cannot support spread spectrum clock spreading.

(3)

Applies only when driven through an external digital oscillator.
