Introduction
The device configuration bits allow each user to customize certain aspects of the device to the
needs of the application. When the device powers up, the state of these bits determines the
modes that the device uses. Subsection
uration bits, and the modes that they can be configured to. These bits are mapped in program
memory location 2007h. This location is not accessible during normal device operation (can be
accessed only during programming mode).
The configuration bits can be programmed (read as '0') or left unprogrammed (read as '1') to
select various device configurations. The ability to change these settings once they have been
programmed depends on the memory technology and the package type.
For Read Only Memory (ROM) devices, these bits are specified at time of ROM code submittal
and once the device is masked may not be changed for those devices (would require a new mask
code).
For One Time Programmable (OTP) devices, once these bits are programmed (’0’), they may not
be changed.
For windowed EPROM devices, once these bits are programmed (’0’), the device must be UV
erased to return the configuration word to the erased state. UV erasing the device also erases
the program memory.
For Flash devices, these bits may be erased and reprogrammed.
Note:
Microchip does not recommend code protecting windowed devices.
