Option bits in this space are altered to change the chip configuration at reset.
OSC_SEL[1:0]—Oscillator mode selection
00 = On-chip oscillator configured for use with external RC networks (<4 MHz).
01 = Minimum power for use with very low frequency crystals (32 kHz to 1.0 MHz).
10 = Medium power for use with medium frequency crystals or ceramic resonators 
(0.5 MHz to 10.0 MHz).
11 = Maximum power for use with high frequency crystals (8.0 MHz to 20.0 MHz). This
setting is the default for unprogrammed (erased) Flash.
WDT_RES—WDT Reset
0 = WDT time-out generates an interrupt request. Interrupts must be globally enabled for
the ZNEO CPU to acknowledge the interrupt request.
1 = WDT time-out causes a Short Reset. This setting is the default for unprogrammed
(erased) Flash.
WDT_AO—WDT always on 
0 = WDT is automatically enabled after reset. The WDT oscillator is disabled by clearing
the WDTEN bit in the OSCCTL register.
1 = WDT is enabled upon execution of the
disabled by clearing the WDTEN bit in the OSCCTL register.
VBO_AO—Voltage Brownout protection always on 
0 = Voltage Brownout protection is disabled in STOP mode to reduce total power 
consumption.
1 = Voltage Brownout protection is always enabled, including during STOP mode. This
setting is the default for unprogrammed (erased) Flash.
DBGUART—Debug UART enable 
0 = The Debug UART option is enabled.
1 = The Debug UART option is disabled.
