Table 8-6 Configuration Register Field Description
BitFieldTypeResetDescription
15 One_ShotR/W0bOne-shot conversion trigger applicable in shutdown mode only. In continuous conversion mode the bit reads 0b. In shutdown mode the bit reads 1b, then after the conversion is finished the bit reads 0b. Triggering a one-shot conversion happens only when the device is in shutdown mode.
0b = Active conversion ongoing
1b = Trigger a one-shot conversion or active conversion complete
14:13ReservedR10bReserved
12:11Fault[1:0]R/W00bFault bits are used to set the number of consecutive conversions for which the alert condition exists before the ALERT pin is asserted and status bit is set.
00b = 1 fault
01b = 2 faults
10b = 4 faults
11b = 6 faults
10PolarityR/W0bThe polarity bit allows the host to adjust the polarity of the ALERT pin/flag output.
0b = ALERT pin/flag output is active low
1b = ALERT pin/flag output is active high
9Alert_ModeR/W0bThe alert mode bit indicates the how the temperature limits operate.
0b = Comparator mode
1b = Alert mode
8ShutdownR/W0bThe shutdown bit is used to change the device conversion mode.
0b = Continuous conversion mode
1b = Shutdown mode
7:6Conversion_Rate[1:0]R/W10bThe conversion rate bits configure the device conversion period. The default is conversion every 250ms.
00b = 4s / 0.25Hz
01b = 1s / 1Hz
10b = 0.25s / 4Hz
11b = 0.125s / 8Hz
5Alert flagR1bThe alert bit is a read-only bit which provides the information about the alert status in comparator mode and is affected by Alert_Mode setting. The polarity bit affects the alert flag.
