8.2 Configuration Register (address = 01h) [reset = 60A0h]

This register is used to configure the operation of the TMP110 and also provides the alert status when ALERT pin is not available on the pin-out.

Table 8-8 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. Triggering a one-shot conversion happens only when the TMP110 is in shutdown mode.
0b = Active conversion ongoing
1b = Trigger a one-shot conversion or active conversion complete
14:13ReservedR11bReserved
12:11Fault[1:0]R/W00bThe fault bit is used to count the number of consecutive conversions for which the alert condition exists before the ALERT pin is asserted or 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 TMP110 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 is a read-only bit which provides the information about the alert status in comparator mode and is not affected by Alert_Mode setting. The polarity bit affects the alert flag.
4Extended_ModeR/W0bThe extended mode bit configures the temperature format.
0b = Normal format with 12-bit
1b = Extended format with 13-bit
