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.

Function :
Set bit 3 in FEExMOD.
Write 0xFFC3 in FEExADR
Write 0x3CFF in FEExDAT
Run the Mass Erase command 0x06 in FEExCON
Description (note x is 0 or 1 to designate Flash/EE Block 0 or 1)
Not Used
These bits are not used and will always read as 0.
Flash 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
FEExMOD register is set
Cleared automatically when the FEExSTA 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 FEExCON completes unsuccessfully
Cleared automatically when the FEExSTA register is read by user code
Command Successful
Set automatically by MCU when a command is completed successfully.
Cleared automatically when the FEExSTA register is read by user code
These 8-bit read only registers can be read by user code and reflect the current status of the Flash/EE memory
controllers.
FEE0ADR and FEE1ADR
0xFFFF0E10 and 0xFFFF0E90
Non Zero
Read/Write Access
This 16-bit register dictates the address
upon which any Flash/EE command
executed via FEExCON will act upon.
FEE0STA and FEE1STA
0xFFFF0E00 and 0xFFFF0E80
0x00
ReadOnly

This sequence is illustrated in the following example,:
FEExMOD= 0x08
FEExADR= 0xFFC3
FEExDAT= 0x3CFF
FEExCON= 0x06;
while (FEExSTA & 0x04){}
Note: To run the mass erase command via FEE0CON, Write
FEE0DAT and FEE1DAT Registers:

Default Value :
Access :
Function :
protection on the lower 64kbytes must be disabled, i.e.
FEE1HIDE/FEE1PRO are set to 0xFFFFFFFF.. This may
be done be first removing the protection or erasing the
lower 64kbytes first.
FEE0DAT and FEE1DAT
0xFFFF0E0C and 0xFFFF0E8C
Non Zero
Read/Write Access
This 16-bit register contains the data either
read from or to be written to the Flash/EE
memory.
//Wait for command to finish
// Mass-Erase command
