Conversion period setting. This bit field changes the conversion
period of the device at the next possible interval but does not
restart an on-going conversion period. Writing an unsupported
value to this setting puts the device in Shutdown mode.
0h = 16s / 0.0625Hz
1h = 8s / 0.125Hz
2h = 4s / 0.25Hz
3h = 2s / 0.5Hz
4h = 1s / 1Hz
5h = 0.5s / 2Hz
6h = 0.25s / 4Hz
7h = 0.125s / 8Hz
8h = 0.0625s / 16Hz
9h-Fh = Unsupported settings. The device goes into the
Shutdown mode.
8.6 THigh_Limit_Local Register (Address = 05h or 0Bh) [reset = 55h]
This register is used to configure Local temperature high limit. The default value 55h corresponds to a limit
setting of 85°C.
