3.5.3.2 Operation of the Configuration Mechanism
The CONFIG register consists of an EEPROM byte and static working latches. This
register controls the start-up configuration of the MCU. The contents of the EEPROM
CONFIG byte are transferred into static working latches during any reset sequence.
The operation of the MCU is controlled directly by these latches and not the actual EE-
PROM byte. Changes to the EEPROM byte do not affect operation of the MCU until
after the next reset sequence. When programming the CONFIG register, the EE-
PROM byte is being accessed. When the CONFIG register is being read, the static
latches are being accessed.
To change the value in the CONFIG register proceed as follows:
1. Erase the CONFIG register.
CAUTION
Do not issue a reset at this time.
2. Program the new value to the CONFIG register.
3. Issue a reset so the new configuration will take effect.
