42 / 58 page  7.6.14 MR30: Temperature Sensor Low Limit-Low Byte Configuration (address = 1Eh) [reset = 00h] The status flag for critical low limit is set when the result of the temperature conversion is less than the programmed value in the MR31 and MR30 registers. The application must ensure that the critical temperature low limit registers must have a value lower than the temperature low limit registers. Return to Register Map. Figure 7-60. MR30: Temperature Sensor Low Limit-Low Byte Configuration Register 7 6 5 4 3 2 1 0 TS_LOW_LIMIT_LOW[7:0] RW-00h R-0 R-0 Table 7-26. MR30: Temperature Sensor Low Limit-Low Byte Field Descriptions Bit Field Type Reset Description 7:0 TS_LOW_LIMIT_LOW[7:0] RW 00h Low byte of the low limit temperature for the thermal sensor.1 MR31 and MR30 together define the low limit for the thermal sensor. 1. The bits marked as R-0, shall not be updated when host writes 1 and shall read as 0. 7.6.15 MR31: Temperature Sensor Low Limit-High Byte Configuration (address = 1Fh) [reset = 00h] The status flag for critical low limit is set when the result of the temperature conversion is less than the programmed value in the MR31 and MR30 registers. The application must ensure that the critical temperature low limit registers must have a value lower than the temperature low limit registers. Return to Register Map. Figure 7-61. MR31: Temperature Sensor Low Limit-High Byte Configuration Register 7 6 5 4 3 2 1 0 TS_LOW_LIMIT_HIGH[7:0] R-0 R-0 R-0 RW-00h Table 7-27. MR31: Temperature Sensor Low Limit-High Byte Field Descriptions Bit Field Type Reset Description 7:0 TS_LOW_LIMIT_HIGH[7:0] RW 00h High byte of the low limit temperature for the thermal sensor.1 MR31 and MR30 together define the low limit for the thermal sensor. 1. The bits marked as R-0, shall not be updated when host writes 1 and shall read as 0. 7.6.16 MR32: Temperature Sensor Critical High Temperature Limit-Low Byte Configuration (address = 20h) [reset = 50h] The status flag for critical temperature high limit is set when the result of the temperature conversion is greater than the programmed value in the MR33 and MR32 registers. The application must ensure that the critical temperature high limit registers must have a value greater than the temperature high limit registers. Return to Register Map. Figure 7-62. MR32: Temperature Sensor Critical Temperature High Limit-Low Byte Configuration Register 7 6 5 4 3 2 1 0 TS_CRIT_HIGH_LIMIT_LOW[7:0] RW-50h R-0 R-0 TMP139 SNIS217 – DECEMBER 2020 www.ti.com 42 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TMP139 |
