ST10F273M
Internal Flash memory
14
SUSP
Suspend
This bit must be set to suspend the current Program (Word or Double Word) or
Sector Erase operation in order to read data in another part of the Flash. The
Suspend operation resets the Bank0 to normal read mode (automatically resetting
bits BSYx). When in Program Suspend, the Flash module accepts only the
following operations: Read and Program Resume. When in Erase Suspend the
module accepts only the following operations: Read, Erase Resume. To resume a
suspended operation, the WMS bit must be set again, together with the selection
bit corresponding to the operation to resume (WPG, DWPG, SER).(1)
13
WPG
Word program
This bit must be set to select the Word (32 bits) Program operation in the Flash
module. The Word Program operation allows to program 0s in place of 1s. The
Flash Address to be programmed must be written in the FARH/L registers, while
the Flash Data to be programmed must be written in the FDR0H/L registers before
starting the execution by setting bit WMS. WPG bit is automatically reset at the
end of the Word Program operation.
12
DWPG
Double word program
This bit must be set to select the Double Word (64 bits) Program operation in the
Flash module. The Double Word Program operation allows to program 0s in place
of 1s. The Flash Address in which to program (aligned with even words) must be
written in the FARH/L registers, while the two Flash Data words to be programmed
must be written in the FDR0H/L registers (even word) and FDR1H/L registers (odd
word) before starting the execution by setting bit WMS. DWPG bit is automatically
reset at the end of the Double Word Program operation.
11
SER
Sector erase
This bit must be set to select the Sector Erase operation. The Sector Erase
operation allows to erase all the Flash locations to value 0xFFFF. From 1 to all of
Bank0’s sectors (excluding Test-Flash) can be selected to be erased through bits
BxFy of FCR1H/L registers before starting the execution by setting bit WMS. It is
not necessary to preprogram the sectors to 0, because this is done automatically.
SER bit is automatically reset at the end of the Sector Erase operation.
10:9
-
Reserved. This bit must be left to their reset value (0).
8
SPR
Set protection
This bit must be set to select the Set Protection operation. The Set Protection
operation allows to program 0s in place of 1s in the Flash Non-Volatile Protection
Registers. The Flash Address in which to program must be written in the FARH/L
registers, while the Flash Data to be programmed must be written in the FDR0H/L
before starting the execution by setting bit WMS. A sequence error is flagged by bit
SEQER of FER if the address written in FARH/L is not in the range 0x0E DFB0-
0x0E DFBF.
SPR bit is automatically reset at the end of the Set Protection operation.
7DSMOD
Dummy Select Module
This is a dummy SMOD bit that is maintaining software compatibility with the
ST10F273E where it must be set before every Write Operation to the IFlash.
It has no effect in the ST10F273M.
6:0
-
Reserved. These bits must be kept to their reset value (0).
1.
It is forbidden to start a new Write operation with bit SUSP already set.
