Param.
D001
The supply voltage specification (parameter
D001) has changed. The new value is shown in
Table 1.
No.
Configuration Word: Code Protection
The function of the Code Protect bits has changed
since engineering samples were provided. Code
protection now functions to protect all, or none of
the FLASH program memory. Partial program
memory code protection is no longer supported in
production marked devices. Current code protec-
tion support is shown in Table 2.
