Watchdog autoload value
(see specification)
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.
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:
Enabled
Disabled
Security Bit #2:
Enabled
Disabled
Encryption:
No
Yes
If Yes, must send key file.
