43).
These option bits enable the voltage detection block (LVD, and AVD):
00: Selected low voltage detector = LVD and AVD on
01: Selected low voltage detector = LVD on and AVD off
10: Selected low voltage detector = LVD and AVD off
11: Selected low voltage detector = LVD and AVD off
This option bit selects the number of CPU cycles applied during the reset phase and
when exiting Halt mode. For resonator oscillators, it is advised to select 4096 due to the
long crystal stabilization time.
0: Reset phase with 4096 CPU cycles
1: Reset phase with 256 CPU cycles
Note: When the PLL clock is selected (CKSEL = 0), the reset clock cycle selection is
forced to 4096 CPU cycles.
1: DIV2 divider disabled with OSC1 (or OSCIN) = 8 MHz
0: DIV2 divider enabled (in order to have 8 MHz required for the PLL with OSC1 (or
Readout protection, when selected provides a protection against program memory
content extraction and against write access to Flash memory. This protection is based
on a read/write protection of the memory in test modes and ICP mode. 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 the ST7 Flash
Programming Reference Manual and
for more details.
