Bit 4 = OSC RC Oscillator selection
0: RC oscillator on
1: RC oscillator off
Note: If the RC oscillator is selected, then to im-
prove clock stability and frequency accuracy, it is
recommended to place a decoupling capacitor,
typically 100nF, between the V
close as possible to the ST7 device.
Bit 1 = WDG SW Hardware or software watchdog
This option bit selects the watchdog type.
0: Hardware (watchdog always enabled)
1: Software (watchdog to be enabled by software)
Bit 0 = WDG HALT Watchdog Reset on Halt
This option bit determines if a RESET is generated
when entering HALT mode while the Watchdog is
active.
0: No Reset generation when entering Halt mode
1: Reset generation when entering Halt mode
