UC3F Operation
The following sections describe the operation of the UC3F EEPROM during various operational modes.
The primary function of the UC3F EEPROM module is to serve as electrically erasable and programmable
non-volatile memory for embedded application in microcontrollers.
21.3.1
Reset
The device signals a reset to the UC3F EEPROM by asserting the reset signal. A reset is the highest
priority operation for the UC3F EEPROM and terminates all other operations. The UC3F EEPROM
module uses reset to initialize register bits to their default reset value. If the UC3F EEPROM is in program
or erase operation (UC3FCTL[EHV] = 1 and UC3FCTL[SES] = 1) and a reset is issued, the module will
perform the needed interlocks to disable the high voltage without damage to the high voltage circuits.
Reset terminates any other mode of operation and forces the UC3F EEPROM module to a state ready to
receive accesses.
