For the common functions, it is expected that the derivative parts will maintain
compatibility to the superset emulation part.
There are multiple issues with the multiplexing controls:
1. For GIOB[2], to take input from the alternate path,the PINMMR29[16] has to cleared.
This is incompatible with the emulation device, where the PINMMR29[16] needs to
be set to select the alternate path as input for GIOB[2].
2. PINMMR29[24] is cleared by default to select MII interface for the EMAC. This is
incompatible with the emulation device, where the PINMMR29[24] was set by default
and selects the RMII interface.
The behavior is not dependent on any particular operating condition.
The application must manage the configuration of the PINMMR registers based on the
actual part being used. The code running on the emulation device cannot be run as-is on
this device.
There are no software workarounds.
