Technical Data
220
In emulation mode, to support emulation of the internal FLASH memory
with external memory devices, the CMFR responds to an array access
only by terminating the access. During emulation, the CMFR does not
drive any data and the data should be provided by an external device.
This synchronizes the timing of 1-clock on-page accesses and 2-clock
off-page accesses during emulation from external memory.
The device signals a master reset to the CMFR when a full reset is
required. A master reset is the highest priority operation for the CMFR
and terminates all other operations. The CMFR uses master reset to
initialize all register bits to their default reset value. If the CMFR is in
program or erase operation (EHV = 1) and a master reset is generated,
the module performs the needed interlocks to disable the high voltage
without damage to the high voltage circuits. Master reset terminates any
other mode of operation and forces the CMFR BIU to a state ready to
receive accesses.
The CMFR does not generate interrupt requests.
