Table 90. Default Values
After programming the part by ISP, the BSB must be cleared (00h) in order to allow the
application to boot at 0000h.
The content of the Software Security Byte (SSB) is described in Table 90 and Table 93.
To assure code protection from a parallel access, the HSB must also be at the required
level.
Table 91. Software Security Byte
Table 92.
The two lock bits provide different levels of protection for the on-chip code and data,
when programmed as shown to Table 93.
