TDA4VM: MCU_RGMII pin drive capability configuration

yixing chen

Part Number: TDA4VM

As show in the figure below，in IBIS model，the pin of MCU_RGMII could be configured with fast，nom and slow drive capabilities

So，how to configure MCU_RGMII pin with fast drive capability

Yixing,

I believe that the fast, slow, nom is related to the process and voltage variation ( 1.8 +/- 0.1V) which can be configured in the IBIS simulation s/w and not to do with configuring the device pins.

as an example of what I see in one of the IBIS s/w I have here.

Yixing,

Pad config registers select the drive strength.

for eg: CTRLMMR_WKUP_PADCONFIG0 bits 20:19. Nom is recommended, but options of fast, and slow.
