41 / 58 page  Table 7-23. MR27: Interrupt Configuration Field Descriptions (continued) Bit Field Type Reset Description 0 IBI_TS_HIGH_EN RW 0 In band interrupt (IBI) enable for temperature sensor high. 0 = Disable. MR51 register TS_HIGH_STATUS bit does not generate an IBI to host. 1 = Enable. MR51 register TS_HIGH_STATUS bit generates an IBI to host. 1. IBI_ERROR_EN can only be updated by ENEC CCC, DISEC CCC, RSTDAA CCC or bus reset sequence. A direct write to the register or through DEVCTRL CCC shall not update the bit and may lead to unpredictable behavior. 7.6.12 MR28: Temperature Sensor High Limit-Low Byte Configuration (address = 1Ch) [reset = 70h] The status flag for temperature high limit is set when the result of the temperature conversion is greater than the programmed value in the MR29 and MR28 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 7-58. MR28: Temperature Sensor High Limit-Low Byte Configuration Register 7 6 5 4 3 2 1 0 TS_HIGH_LIMIT_LOW[7:0] RW-70h R-0 R-0 Table 7-24. MR28: Temperature Sensor High Limit-Low Byte Field Descriptions Bit Field Type Reset Description 7:0 TS_HIGH_LIMIT_LOW[7:0] RW 70h Low byte of the high limit temperature for the thermal sensor.1 MR29 and MR28 together define the high 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. 7.6.13 MR29: Temperature Sensor High Limit-High Byte Configuration (address = 1Dh) [reset = 03h] The status flag for temperature high limit is set when the result of the temperature conversion is greater than the programmed value in the MR29 and MR28 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 7-59. MR29: Temperature Sensor High Limit-High Byte Configuration Register 7 6 5 4 3 2 1 0 TS_HIGH_LIMIT_HIGH[7:0] R-0 R-0 R-0 RW-03h Table 7-25. MR29: Temperature Sensor High Limit-High Byte Field Descriptions Bit Field Type Reset Description 7:0 TS_HIGH_LIMIT_HIGH[7:0] RW 03h High byte of the high limit temperature for the thermal sensor.1 MR29 and MR28 together define the high 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. www.ti.com TMP139 SNIS217 – DECEMBER 2020 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 41 Product Folder Links: TMP139 |
