What is the maximum capacity of MMC card we can connect to MPC8569?

It's Reference manual ( MPC8569ERM Rev. 2  06/2011) mentions that it can support SDHC from 4GB to 32GB but what about the MMC size?

Have a great day,

The MPC8569 eSDHC is compatible with MultiMediaCard System Specification, Version 4.2 and SD Memory Card Specification, Version 2.0. The MMC spec. ver 4.2 does not specify maximal capacity in the block address mode. While the SD spec. ver. 2.0 specifies max card capacity. So in accordance to the MMC spec. ver 4.2 the MPC8569 supports MMC max capacity:
     2GB   -  Byte Address Mode
  > 2GB  -  Block Address Mode
