OPTION BYTES (cont’d)
15.1.1 Option Byte 0
OPT7 = AWUCK Auto Wake Up Clock Selection
0: 32 kHz oscillator (VLP) selected as AWU clock
1: AWU RC oscillator selected as AWU clock.
Note: If this bit is reset, internal RC oscillator must
be selected (Option OSC = 0).
OPT6:4 = OSCRANGE[2:0] Oscillator Range
When the internal RC oscillator is not selected
(Option OSC = 1), these option bits select the
range of the resonator oscillator current source or
the external clock source.
Note: OSCRANGE[2:0] has no effect when
AWUCK option is set to 0. In this case, the VLP os-
cillator range is automatically selected as AWU
clock.
For Flash devices
OPT 3:2 = SEC[1:0] Sector 0 size definition
These option bits indicate the size of sector 0 ac-
cording to the following table.
OPT1 = FMP_R Readout protection
Readout protection, when selected provides a pro-
tection against program memory content extrac-
tion and against write access to Flash memory.
Erasing the option bytes when the FMP_R option
is selected will cause the whole memory to be
erased first and the device can be reprogrammed.
Refer to the ST7 Flash Programming Reference
Manual and section 4.5 on page 15 for more de-
tails
0: Readout protection off
1: Readout protection on
OPT 0 = FMP_W Flash write protection
This option indicates if the Flash program memory
is write protected.
Warning: When this option is selected, the pro-
gram memory (and the option bit itself) can never
be erased or programmed again.
0: Write protection off
1: Write protection on
The option bytes have no address in the memory
map and are accessed only in programming mode
(for example using a standard ST7 programming
tool). The default content of the Flash is fixed to
FFh.
For ROM devices
OPT 3:2 = Reserved [1:1]
OPT1 = ROP_R Readout protection for ROM
This option is for read protection of ROM
0: Readout protection off
1: Readout protection on
OPT 0 = ROP_D Readout protection for Data
EEPROM
This option is for read protection of EEPROM
memory.
0: Readout protection off
1: Readout protection on
