DEVICE CONFIGURATION (Cont’d)
OPT 0 = FMP_W FLASH write protection
This option indicates if the FLASH program mem-
ory is write protected.
Warning: When this option is selected, the pro-
gram memory (and the option bit itself) can never
be erased or programmed again.
0: Write protection off
1: Write protection on
USER OPTION BYTE 1
OPT 7 = EXTIT Port C External Interrupt Configu-
ration.
This option bit allows the Port C external interrupt
mapping to be configured as ei0 or ei1.
Table 27. External Interrupt Configuration
OPT 6 = Reserved, must be kept at default value.
OPT 5:4 = OSCTYPE[1:0] Oscillator Type selec-
tion
These option bits select the Oscillator Type.

OPT 3:1 = OSCRNGE[2:0] Oscillator Range se-
lection
These option bits select the oscillator range.
OPT 0 = PLL PLL selection
This option bit selects the PLL which allows multi-
plication by two of the oscillator frequency. The
PLL must not be used with the internal RC oscilla-
tor. It is guaranteed only with a f
cy between 2 and 4MHz.
0: PLL x2 enabled
1: PLL x2 disabled
CAUTION: the PLL can be enabled only if the
“OSC RANGE” (OPT3:1) bits are configured to
“MP - 2~4MHz”. Otherwise, the device functionali-
ty is not guaranteed.
