FLASH OPTION BYTES (Cont’d)
OPT2:1 = PKG[1:0] Package selection
These option bits select the device package.
Note: Pads that are not bonded to external pins
are in input pull-up configuration when the pack-
age selection option bits have been properly pro-
grammed. The configuration of these pads must
be kept in reset state to avoid added current con-
sumption.
OPT0 = FMP_R Flash memory read-out protec-
tion
Read-out protection, when selected provides a
protection against program memory content ex-
traction and against write access to Flash memo-
ry. Erasing the option bytes when the FMP_R op-
tion is selected causes the whole user memory to
be erased first, and the device can be repro-
grammed. Refer to
Flash Programming Reference Manual for more
details.
0: Read-out protection enabled
1: Read-out protection disabled
OPTION BYTE 1
OPT7:6 = AFI_MAP[1:0] AFI Mapping
These option bits allow the mapping of some of the
Alternate Functions to be changed.

OPT5:4 = OSCTYPE[1:0] Oscillator Type
These option bits select the ST7 main clock
source type.
OPT3:2 = OSCRANGE[1:0] Oscillator range
If the resonator oscillator type is selected, these
option bits select the resonator oscillator. This se-
lection corresponds to the frequency range of the
resonator used. If external source is selected with
the OSCTYPE option, then the OSCRANGE op-
tion must be selected with the corresponding
range.
OPT1 = Reserved
OPT0 = RSTC RESET clock cycle selection
This option bit selects the number of CPU cycles
inserted during the RESET phase and when exit-
ing HALT mode. For resonator oscillators, it is ad-
vised to select 4096 due to the long crystal stabili-
zation time.
0: Reset phase with 4096 CPU cycles
1: Reset phase with 256 CPU cycles
