DS90UB925Q-Q1: selecting internal oscillator for OSC clock source

K.Yaita

Part Number: DS90UB925Q-Q1

Hi Team,

I believe internal oscillator is selected for OSC clock source when I set the following register regardless of external PCLK is supplied.

- 0x03[1] = 0 (Disable auto-switch)
- 0x14[2:1] = 01 (33 MHz Oscillator)

Is my understanding correct?

Hello,
If you disable the auto-switch then the 925 will NOT default to the internal oscillator when PCLK is not present.
Regards.
