Hardware power down
(1)Internal oscillator is designed to give nominally 8-MHz clock frequency. However, due to process variations, this frequency can vary from device
to device. All calculations for delays and wait times in the data sheet assume an 8-MHz oscillator clock.
(2)It is recommended that AVDD and DRVDD be set to the same voltage for the best performance. It is also recommended that these supplies be
separated on the user’s PCB.
