Device configuration

Note:
162/171
When the internal RC oscillator is selected, the OSCRANGE option bits must be kept at
their default value in order to select the 256 clock cycle delay (see
OPT3:2 = SEC[1:0] Sector 0 size definition
These option bits indicate the size of sector 0 according to the following table.
Table 96.
OPT1 = FMP_R Readout protection
Readout 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 will cause the whole memory to be erased first and the device can
be reprogrammed. Refer to the ST7 Flash Programming Reference Manual and
on page 21
0: Readout protection off
1: Readout protection on
OPT0 = FMP_W FLASH write protection
This option indicates if the FLASH program memory is write protected.
When this option is selected, the program memory (and the option bit itself) can never be
erased or programmed again.
0: Write protection off
1: Write protection on
Option byte 1
OPT7 = PLLx4x8 PLL Factor selection.
0: PLLx4
1: PLLx8
OPT6 = PLLOFF PLL disable.
0: PLL enabled
1: PLL disabled (by-passed)
OPT5 = PLL32OFF 32MHz PLL disable.
0: PLL32 enabled
1: PLL32 disabled (by-passed)
OPT4 = OSC RC Oscillator selection
0: RC oscillator on
1: RC oscillator off
If the RC oscillator is selected, then to improve clock stability and frequency accuracy, it is
recommended to place a decoupling capacitor, typically 100 nF, between the V
pins as close as possible to the ST7 device.
