2.3.3.1 System Configuration Register
The system configuration register (CONFIG) consists of an EEPROM byte and static latches that control
the startup configuration of the MCU. The contents of the EEPROM byte are transferred into static
working latches during reset sequences. The operation of the MCU is controlled directly by these latches
and not by CONFIG itself. In normal modes, changes to CONFIG do not affect operation of the MCU until
after the next reset sequence. When programming, the CONFIG register itself is accessed. When the
CONFIG register is read, the static latches are accessed. See
Programming and Erasure
To take full advantage of the MCU’s functionality, customers can program the CONFIG register in
bootstrap mode. This can be accomplished by setting the mode pins to logic 0 and downloading a small
program to internal RAM. For more information, Freescale application note AN1060 entitled
Bootstrap Mode
All of this functionality is provided by PCbug11 which can be found on the Freescale Web site at
http://www.freescale.com. For more information on using PCbug11 to program an E-series device,

Operation of the CONFIG register in the MC68HC811E2 differs from other devices in the M68HC11 E
series. See

Resets:
U indicates a previously programmed bit. U(L) indicates that the bit resets to the logic level held in the latch prior to reset,
but the function of COP is controlled by the DISR bit in TEST1 register.
