ROM CODE SUBMISSION FOR 16K ROM DEVICES (87C51RB2)
When submitting ROM code for the 16K ROM devices, the following must be specified:
1. 16 kbyte user ROM data
2. 64 byte ROM encryption key
3. ROM security bits.

ROM Security Bit 2
0 = enable security
1 = disable security
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:
Security Bit #1:
V Enabled
V Disabled
Security Bit #2:
V Enabled
V Disabled
Encryption:
V No
V Yes
If Yes, must send key file.
