Non-Volatile Memory FLASH (CMFR)<br />

9.8.7 Emulation Operation<br />

In emulation mode, to support emulation of the internal FLASH memory<br />

with external memory devices, the CMFR responds to an array access<br />

only by terminating the access. During emulation, the CMFR does not<br />

drive any data and the data should be provided by an external device.<br />

This synchronizes the timing of 1-clock on-page accesses and 2-clock<br />

off-page accesses during emulation from external memory.<br />

9.9 Master Reset<br />

9.10 Interrupts<br />

The device signals a master reset to the CMFR when a full reset is<br />

required. A master reset is the highest priority operation for the CMFR<br />

and terminates all other operations. The CMFR uses master reset to<br />

initialize all register bits to their default reset value. If the CMFR is in<br />

program or erase operation (EHV = 1) and a master reset is generated,<br />

the module performs the needed interlocks to disable the high voltage<br />

without damage to the high voltage circuits. Master reset terminates any<br />

other mode of operation and forces the CMFR BIU to a state ready to<br />

receive accesses.<br />

The CMFR does not generate interrupt requests.<br />
