Table 9-3.
After programming the part by ISP, the BSB must be cleared (00h) in order to allow the applica-
tion to boot at 0000h.
The content of the Software Security Byte (SSB) is described in
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 pro-
grammed as shown to Table 9-5.
