Table 33: Write/read protection of configuration
With CFGPROT = ’0’, the registers at the addresses
0x00 to 0x0F and 0x78 to 0x7F are readable and write-
able. The addresses 0x10 to 0x1F and 0x77 are read-
-only. With CFGPROT = ’1’, all registers except the
addresses 0x7B and 0x7C are write-protected; the ad-
dresses 0x77 to 0x7F are readable, while all others are
read-protected.
