Does MPC5777C device offers 23 address lines in non-multiplexed mode?
When non-multiplexed mode has been choosen, bits 9-30 will be reflected on the external bus D_ADD [9:30]. There is 22 address line thus maximum memory size is 8Mbytes (=2^23 because of 16-bit data bus and so D_ADD31 is not used) per chip select.

Hi, 22 address lines. ADD31 is basically replaced by two byte strobe lines because 16-bit data port.
ok thank you
