15 DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in a user
programmable version (FLASH). FLASH devices
are shipped to customers with a default program
memory content (FFh). The OSC option bit is pro-
grammed to 0 by default.
15.1 OPTION BYTES
The two option bytes allow the hardware configu-
ration of the microcontroller to be selected.
The option bytes can be accessed only in pro-
gramming mode (for example using a standard
ST7 programming tool).
OPTION BYTE 0
Bit 7:4 = Reserved, must always be 1.
Bit 3:2 = SEC[1:0]
Sector 0 size definition
These option bits indicate the size of sector 0 ac-
cording to the following table.
Bit 1 = FMP_R
Read-out protection
This option indicates if the FLASH program mem-
ory and Data EEPROM is protected against pira-
cy. The read-out protection blocks access to the
program and data areas in any mode except user
mode and IAP mode. Erasing the option bytes
when the FMP_R option is selected will cause the
whole memory to be erased first.
0: Read-out protection off
1: Read-out protection on
Bit 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
OPTION BYTE 1
Bit 7 = PLLx4x8
PLL Factor selection.
0: PLLx4
1: PLLx8
Bit 6 = PLLOFF
PLL disable.
0: PLL enabled
1: PLL disabled (by-passed)
Bit 5 = Reserved, must always be 1.
Bit 4 = OSC
RC Oscillator selection
0: RC oscillator on
1: RC oscillator off
