TMS320F28069M: VREFHI pin analog circuit equivalent

Part Number: TMS320F28069M

Hi,

Can you confirm whether the VREFHI pin is buffered or whether it is sampled with an ADC switching capacitor just like the analog input pins? In figure 1.5 it appears to be buffered with an op amp.

Best regards,

Sean
