GPIO operating voltage in LS1046

[Urmila_123]

Hi all,

It is clear from LS1046A data sheet that we will be able to operate GPIO pins either at EVDD or TVDD or OVDD or  LVDD. So, How can we fix one specific Voltage? is there any register or RCW field? or Can we apply directly? Please Clarify.

Thanks & Regards

In the QorIQ LS1046A, LS1026A Data Sheet, Table 1. Pinout list by bus it is specified which exactly supply voltage is used by specific GPIO.

Common voltage supported by all of OVDD, EVDD, DVDD, TVDD and LVDD  is 1.8V, so it is possible to apply 1.8V to supply powering specific GPIO.
