EPROM CHARACTERISTICS
The XA-S3 is programmed by using a modified Improved
Quick-Pulse Programming
the same as that used by 80C51 family EPROM parts. However
different pins are used for many programming functions.
The XA-S3 contains three signature bytes that can be read and
used by an EPROM programming system to identify the device. The
signature bytes identify the device as an XA-S3 manufactured by
Philips.

PROTECTION DESCRIPTION
No Program Security features enabled.
MOVC instructions executed from external program memory are disabled from fetching code bytes
from internal memory and further programming of the EPROM is disabled.
Same as 2, also verify is disabled.
Same as 3, external execution is disabled. Internal data RAM is not accessible.

Security Bits
With none of the security bits programmed the code in the program
memory can be verified. When only security bit 1 is programmed,
MOVC instructions executed from external program memory are
disabled from fetching code bytes from the internal memory. All
further programming of the EPROM is disabled. When security bits
1 and 2 are programmed, in addition to the above, verify mode is
disabled. When all three security bits are programmed, all of the
conditions above apply and all external program memory execution
is disabled. (See Table 6.)
