must be placed as close as possible to the pins. Refer to
capacitor values according to the external oscillator frequency.
Table 8.
1. First harmonic resonance frequency.
2. Lower ESR value allows the driving of greater load capacitors.
If a direct clock source is used, it must be connected to the OSCIN pin and the OSCOUT pin
supplies the inverted OSCIN signal (see
Figure 12. OSCIN and OSCOUT pin configuration
When OSCIN is UNUSED, it should be left floating.
When OSCOUT is UNUSED, it should be left floating.
Overcurrent detection
When the current in any of the Power MOSFETs exceeds a programmed overcurrent
threshold, the STATUS register OCD flag is forced low until the overcurrent event has
