hi,
 
this is my first time using MPU module. we're also using xgate code.
1. my first concern is regarding the descriptors - how do i assign descriptors for xgate code, s12code, s12 ram, xgate ram...? should both xgate and s12code be in a single descriptor as well as their RAM?
 
2. how do i configure the start address (ex. s12code) and end address?
 
3. should the EEPROM be covered?
 
4. is there going to a separate descriptor for the PAGED and UNPAGED memory region?
 
and lastly.
 
5. how do i monitor an access violation error from xgate or cpu?
 
a flow algorithm or any info is very much welcome.
