Dear Support-team,

We have below questions about USBPHYLDO of PF1510.
Please support us.

 

<Question 1>
USBPHY (default 3.3 V output) seems to be described as being enable / disable with USBPHYLDO bit,
In the datasheet, USBPHYLDO = '0' for both Enable and Disable.
*The datasheet  of PF 1550 is also the same description.

Is Enable / Disable control possible? (Is it a typo)?

 

<Question 2>
If it is set to Disable, will the USBPHY output become 0 V?

 

Best Regards,
T.Sakamoto@Ryosan
