Table 41. Software Registers
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 42
and Table 43.
To assure code protection from a parallel access, the HSB must also be at the required
level.
The two lock bits provide different levels of protection for the on-chip code and data,
when programmed as shown to Table 43.
