External Program Memory ignored when EA = 0
|
|
|
|
The external Program Memory is always ignored when EA = 0 with the t8048 system
|
|
toplevel. Desired behaviour is to access external Program Memory when code
|
|
has to be fetched from an address location that is outside the internal
|
|
Program Memory.
|
|
|
|
Fixed in t8048.vhd 1.3
|
|
Fix will be included in next release.
