The ECON register is used to configure the user selectable clock, security, RAM size,
power-on reset, WATCHDOG, and HALT options. The register can be programmed and
read only in EPROM programming mode. Therefore, the register should be programmed
at the same time as the program memory. The contents of the ECON register shipped
from the factory read 00 Hex (windowed device) or 80 Hex (OTP device).
The format of the ECON register is as follows:
2.8.5
There are 8 bytes of user storage space in the EPROM that are not read protected by the
security bit in the ECON register. When the security bit in the ECON register is set, data
in User Storage Space is write-enabled, and read-enabled. This allows the user to read
and write this information while still protecting the main EPROM from tampering.
The 8 bytes of user storage space are outside the normal address range of the device, and
cannot be accessed by software. This allows for the storage of non-secure information.
Typical uses of this are serial numbers, date codes, copyright informations, software
version, or lot numbers.
