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.

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

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.
