FEE0CON Register
Name:
FEE0CON
Address:
0xFFFF0E08
Default Value:
0x07
Access:
Read/write access
Function:
This 8-bit register is written by user code to control the operating modes of the Flash/EE memory controller.
Table 13. Command Codes in FEE0CON
Code
Command
Description
0x001
Reserved
Reserved. This command should not be written by user code.
0x011
Single read
Load FEE0DAT with the 16-bit data indexed by FEE0ADR.
0x021
Single write
Write FEE0DAT at the address pointed by FEE0ADR. This operation takes 50 μs.
0x031
Erase write
Erase the page indexed by FEE0ADR and write FEE0DAT at the location pointed by FEE0ADR. This
operation takes 20 ms.
0x041
Single verify
Compare the contents of the location pointed by FEE0ADR to the data in FEE0DAT. The result of
the comparison is returned in FEE0STA Bit 1.
0x051
Single erase
Erase the page indexed by FEE0ADR.
0x061
Mass erase
Erase 30 kB of user space. The 2 kB kernel is protected. This operation takes 1.2 sec. To prevent
accidental execution, a command sequence is required to execute this instruction; this is described
0x07
Idle
Default command.
0x08
Reserved
Reserved. This command should not be written by user code.
0x09
Reserved
Reserved. This command should not be written by user code.
0x0A
Reserved
Reserved. This command should not be written by user code.
0x0B
Signature
This command results in a 24-bit, LFSR-based signature being generated and loaded into FEE0SIG.
If FEE0ADR is less than 0x87800, this command results in a 24-bit, LFSR-based signature of the
user code space from the page specified in FEE0ADR upwards, including the kernel, security bits,
and Flash/EE key.
If FEE0ADR is greater than 0x87800, the kernel and manufacturing data is signed. This operation
takes 120 μs.
0x0C
Protect
This command can be run one time only. The value of FEE0PRO is saved and can be removed only
with a mass erase (0x06) or with the software protection key.
0x0D
Reserved
Reserved. This command should not be written by user code.
0x0E
Reserved
Reserved. This command should not be written by user code.
0x0F
Ping
No operation, interrupt generated.
1 The FEE0CON register reads 0x07 immediately after the execution of this command.
