Device configuration
Each device is available for production in user programmable versions (FLASH) as well as in
factory coded versions (FASTROM).
ST7FDALI devices are FLASH versions. ST7PDALI devices are Factory Advanced Service
Technique ROM (FASTROM) versions: they are factory programmed FLASH devices.
ST7FDALI devices are shipped to customers with a default program memory content (FFh),
while FASTROM factory coded parts contain the code supplied by the customer. This
implies that FLASH devices have to be configured by the customer using the Option Bytes
while the FASTROM devices are factory configured.
Option bytes
The two option bytes allow the hardware configuration of the microcontroller to be selected.
The option bytes can be accessed only in programming mode (for example using a standard
ST7 programming tool).
Option byte 0
OPT7 = Reserved, must always be 1.
OPT6:4 = OSCRANGE[2:0] Oscillator range
When the internal RC oscillator is not selected (Option OSC=1), these option bits select the
range of the resonator oscillator current source or the external clock source.
