Bypass Indicator.
Indicates when the dc-dc converter is operating in bypass mode. Only available on
‘F912 and ‘F902 devices.
0: DC0 is not operating in bypass mode.
1: DC0 is operating in bypass mode.
Selects the bypass settings. Only available on ‘F912 and ‘F902 devices.
00: Bypass mode disabled (highest supply current when the input voltage exceeds
the programmed output voltage).
01: Bypass enabled (auto switch), dc-dc oscillator enabled (fast response time)
10: Bypass enabled (auto switch), dc-dc oscillator disabled (reduced supply current)
11: The dc-dc converter is forced into bypass mode (lowest supply current when the
input voltage exceeds the programmed output voltage).
Passive Diode Mode Enable.
Passive external diode mode. Only available on ‘F912 and ‘F902 devices.
0: Passive diode mode disabled.
1: Passive diode mode enabled.
