Device configuration and ordering information
Caution: The PLL can be enabled only if the “OSC RANGE” (OPT11:10) bits are configured to “MP -
2~4 MHz”. Otherwise, the device functionality is not guaranteed.

Note:
Pads that are not bonded to external pins are in input pull-up configuration when the
package selection option bits have been properly programmed. The configuration of these
pads must be kept in reset state to avoid added current consumption.
OPT0 = FMP_R Flash memory read-out protection
Read-out protection, when selected provides a protection against program memory content
extraction and against write access to Flash memory. Erasing the option bytes when the
FMP_R option is selected causes the whole user memory to be erased first, and the device
can be reprogrammed. Refer to Section 3.3.1: Read-out protection and the ST7 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.
