Some XMEGA processors have an EBI. The following circuit shows how to set up the EBI for 8 bit bus mode where the SRAM can be selected with a jumper.

The BASCOM setup code :

   ' All EBI-Ports must be set to OUTPUT

   ' All Ports, ACTIVE-LOW , must be set to 1 !!!

   ' All Ports, ACTIVE-HIGH, must be set to 0 !!!

   Portj_dirset = &B1111_1111 : Portj = &B1111_1111

   Portk_dirset = &B1111_1111 : Portk = &B1111_1111

 

 

Config Xram = 3port , Ale = Ale12 , Sdbus = 8 , Modesel0 = Sram , Adrsize0 = 256b , Waitstate0 = 4 , Baseadr0 = &H10000 , _
