Q1. What exactly does "Ignored if GPIOx_CFG = 11" mean? (MC33772 data sheet)

Does this mean that if I set GPIOx as a digital output, the GPIOx_DR command is ignored?

 

Q2. The description of GPIO_CFG2[GPIOx_DR] is different in the two datasheets below. Are GPIO_CFG2[GPIOx_DR] of MC33771A and GPIO_CFG2[GPIOx_DR] of MC33772B functionally different?

-MC33771A : GPIOx pin drive. Valid only when GPIOx_CFG = 11 (normal mode), functional in diagnostic mode for OT/ UT diagnostics.

-MC33772B : GPIOx pin drive. Ignored if GPIOx_CFG = 11

1: Yes.

2: I don't have MC33771A datasheet,but for the GPIOx_DR descript are same in datasheet MC33771B/ MC22337B/MC33771C.
