SIU_PCR117.[DSC] cannot be set to 11b

[ORaissouni]

Hi Gyus,

On MPC5777c, we need to configure GPIO ID 117 with DSC set to its Maximum Drive Length; SIU_PCR117.[DSC]=11b. However, it cannot be set at all. The DSC is kept set to 00b.

Any explanation ?

Best regards

Omar

Hi,

this pin is Slow/Medium pad type and so PCR.SRC is controlling its slew rate, a DSC field is reserved, applicable for Fast type pads only.
