== Amstrad ASIC PPI ==
*The 8255 PPI is not emulated by the Pre-ASIC. These CPC’s CPCs have a real PPI chip and therefore behave like the first generation of CPC’sCPCs.
*The ASIC PPI does not support Group Modes other than Groupe Mode 0.
*On the ASIC PPI, Port B is always defined as input and Port C is always defined as output.
