Assigned to the flash memory is the Flash Control Register (FCR) providing status
information and control flags. The status register contains 11 bits of information:
WE
Flash Write Enable Bit
Status
EE
Flash Erase Enable Bit
BUSY
Flash Busy Bit
PROT
Flash Read Protection Activation Bit
CVPP
Flash Control Vpp Bit
PPREV
Flash Revelation Bit
KCTL
Internal Flash Timer Clock Control
DWW
Word/ Double Word Writing Bit
E
Bank Erase Select (2 bits)
FWSET
Flash Writing Mode Set Bit
With the command status“ the present configuration and the status of the Flash memory
can be inspected. The successful completion is indicated by returning to the stand by
mode of the shell. To inspect the status register, the file status.hex is downloaded into the
target. It contains the status register inspection routine, the routine to unlock the Flash
register and a wait routine. Finally, the controller transmits the content of the FCR to the
host where it is displayed.
Actually, the FCR is a virtual register mapped into the active address space of the Flash
memory while the Flash writing mode is active. In order to enable access to the FCR, the
writing mode must be entered by means of the unlock sequence:
mov
Rn,#4000
; Initialize Flash pointer
mov
DPP1:POF FCR, Rn
; First pass of unlock sequence
mov
[Rn], Rn
; Second pass of unlock sequence
After waiting 10us, the FCR can be retrieved by any direct access to an even address in
the active address space of the Flash memory. Writing mode is quitted again by the key
instruction
mov MEM, Rn.
MEM
denotes a memory location within the Flash memory and Rn denotes an arbitrary
register.
