Security Bits
With none of the security bits programmed the code in the program
memory can be verified. If the encryption table is programmed, the
code will be encrypted when verified. When only security bit 1 (see

NOTES:
80C51X2 ROM CODE SUBMISSION
When submitting a ROM code for the 80C51X2, the following must be specified:
1. 4 kbyte user ROM data
2. 64 byte ROM encryption key
3. ROM security bits.
Security Bit 1: When programmed, this bit has two effects on masked ROM parts:
1. External MOVC is disabled, and
2. EA is latched on Reset.
Security Bit 2: When programmed, this bit inhibits Verify User ROM.
NOTE: Security Bit 2 cannot be enabled unless Security Bit 1 is enabled.
If the ROM Code file does not include the options, the following information must be included with the ROM code.
For each of the following, check the appropriate box, and send to Philips along with the code:
80C52X2 ROM CODE SUBMISSION
When submitting a ROM code for the 80C52X2, the following must be specified:
1. 8 kbyte user ROM data
2. 64 byte ROM encryption key
3. ROM security bits.

PROTECTION DESCRIPTION
No Program Security features enabled.
(Code verify will still be encrypted by the Encryption Array if programmed.)
MOVC instructions executed from external program memory are disabled from fetching code bytes from
internal memory, EA is sampled and latched on Reset, and further programming of the EPROM is disabled.
