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

OPT4 = OSC RC Oscillator selection
0: RC oscillator on
1: RC oscillator off
Notes:
1. 1% RC oscillator available on ST7LITE25 and
ST7LITE29 devices only
2. If the RC oscillator is selected, then to improve
clock stability and frequency accuracy, it is recom-
mended to place a decoupling capacitor, typically
100nF, between the V
possible to the ST7 device.

These option bits enable the LVD block with a se-
lected threshold as shown in
Table 23. LVD Threshold Configuration
OPT1 = WDG SW Hardware or Software
Watchdog
This option bit selects the watchdog type.
0: Hardware (watchdog always enabled)
