Preliminary Technical Data
Command Sequence for Executing a Mass Erase
Giving the significance of the ‘Mass Erase’ command, a specific
code sequence must be executed to initiate this operation.

Set bit 3 in FEE0MOD.
Write 0xFFC3 in FEE0ADR
Write 0x3CFF in FEE0DAT
Run the Mass Erase command 0x06 in FEE0CON
Description
Not Used
These bits are not used and will always read as 0.
Flash/EE Interrupt Status Bit
Set automatically when an interrupt occurs, i.e. when a command is complete and the Flash/EE interrupt enable bit in the
FEE0MOD register is set
Cleared automatically when the FEE0STA register is read by user code
Flash/EE controller busy
Set automatically when the Flash/EE controller is busy
Cleared automatically when the controller is not busy
Command Fail
Set automatically when a command written to FEE0CONcompletes unsuccessfully
Cleared automatically when the FEE0STA register is read by user code
Command Successful
Set automatically by MCU when a command is completed successfully
Cleared automatically when the FEE0STA register is read by user code
FEE0STA
0xFFFF0E00
0x20
Read Only
This 8-bit read only register can be read by user code and reflect the current status of the Flash/EE memory controller.

This sequence is illustrated in the following example:
FEE0MOD= 0x08
FEE0ADR= 0xFFC3
FEE0DAT= 0x3CFF
FEE0CON= 0x06;
while (FEE0STA & 0x04){} //Wait for command to finish
// Mass-Erase command
