Bit Description
31 Read Protection.
Cleared by user to protect the 64 kB Flash/EE Block code via JTAG read access.
Set by user to allow reading the 64 kB Flash/EE Block code via JTAG read access.
30 Read Protection. This bit write protects eight pages and each page consists of 512 bytes.
When set by user code, these bits unprotect Page 120 to Page 127 of the 64 kB Flash/EE code memory.
When cleared by user code, these bits write protect Page 120 to Page 127 of the 64 kB Flash/EE code memory.
29 to 0 Write Protection Bits.
When set by user code, these bits unprotect Page 0 to Page 119 of the 64 kB Flash/EE code memory. Each bit write protects four
pages and each page consists of 512 bytes.
When cleared by user code, these bits write protect Page 0 to Page 119 of the 64 kB Flash/EE code memory. Each bit write protects
two pages and each page consists of 512 bytes.
