In PAC-Designer 5.1 and 5.2 the Enhanced Meta Files (.emf) were released with the incorrect names and the utility fails to load them. To fix this situation, rename the following files which are located in the \Macro folder of the PAC-Designer install:
ispClock_5406_I2C_OutGroup_BI_Sch.emf
ispClock_5406_I2C_OutGroup_LI_Sch.emf
ispClock_5406_I2C_OutGroup_UI_Sch.emf
ispClock_5406_I2C_OutGroup_Sch.emf
ispClock_5406_I2C_PLL_Sch.emf
Simply edit the device number fo the filename from 5406 to 5400 so they should look like the following:
ispClock_5400_I2C_OutGroup_BI_Sch.emf
ispClock_5400_I2C_OutGroup_LI_Sch.emf
ispClock_5400_I2C_OutGroup_UI_Sch.emf
ispClock_5400_I2C_OutGroup_Sch.emf
ispClock_5400_I2C_PLL_Sch.emf
The utility will now be able to display the schematics with the text.
