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
Bit Field Type Reset Description
15 One_Shot R/W 0b One-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
14:13 Reserved R 11b Reserved
12:11 Fault[1:0] R/W 00b The 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
10 Polarity R/W 0b The 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
9 Alert_Mode R/W 0b The alert mode bit indicates the how the temperature limits operate.
0b = Comparator mode
1b = Alert mode
8 Shutdown R/W 0b The shutdown bit is used to change the device conversion mode.
0b = Continuous conversion mode
1b = Shutdown mode
7:6 Conversion_Rate[1:0] R/W 10b The conversion rate bits configure the TMP110 conversion period. The default is conversion every 250 ms.
00b = 4 s / 0.25 Hz
01b = 1 s / 1 Hz
10b = 0.25 s / 4 Hz
11b = 0.125 s / 8 Hz
5 Alert flag R 1b The 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.
4 Extended_Mode R/W 0b The extended mode bit configures the temperature format.
0b = Normal format with 12-bit
1b = Extended format with 13-bit
3:0 Reserved R 0000b Reserved
