For example, how does the pin diagram of MPC5748G correspond to the relationship of portpinPCR * in the figure
Hi,
you can see that in IO Signal Table:
Term PortPinPcr comes from MPC56xx devices when the register was called Pad Configuration Register (PCR). In case of MPC57xx, it's called Multiplexed Signal Configuration Register (MSCR).
