46 / 63 page  8.32 TCRIT_Limit_Status Register (Address = 37h) [reset = 00h] The TCRIT_Limit_Status Register contains the status bits that are set when a temperature channel's TCRIT limit is exceeded. If any of these bits are set, the TCRIT status bit in the Status Register is also set, and the TCRIT pin is asserted low. Reading from the TCRIT_Limit_Status Register does not clear the bits in the register. Once the temperature drops below TCRIT limit minus the TCRIT hysteresis, the corresponding status bit is automatically cleared. The TCRIT bit in Status Register is also automatically cleared when all individual channel bits are cleared in the TCRIT_Limit_Status register. Return to Register Map. Figure 8-32.

TCRIT_Limit_Status Register Field Descriptions Bit Field Type Reset Description 7:3 Reserved R 00h Reserved 2 Ch2_TCRIT R 0h This bit is set when the remote temperature channel 2 exceeds the configured TCRIT limit. 1 Ch1_TCRIT R 0h This bit is set when the remote temperature channel 1 exceeds the configured TCRIT limit. 0 Local_TCRIT R 0h This bit is set when the local temperature channel exceeds the configured TCRIT limit. 8.33 Filter_Control Register (Address = 40h) [reset = 00h] This register controls the remote diode filter level. Return to Register Map. Figure 8-33. Filter_Control Register 7 6 5 4 3 2 1 0 Reserved Filter_Control[1:0] R-00h R/W-0h Table 8-36. Filter_Control Register Field Descriptions Bit Field Type Reset Description 7:2 Reserved R 00h Reserved 1:0 Filter_Control[1:0] R/W 0h Controls the filter level. The filter is a moving average of the Remote temperature conversion results. 0h = 0 moving average (default) 1h = 4 moving average (level 1) 2h = 4 moving average (level 1) 3h = 8 moving average (level 2) TMP4719 SBOSAJ7A – OCTOBER 2025 – REVISED DECEMBER 2025 www.ti.com 46 Submit Document Feedback Copyright © 2025 Texas Instruments Incorporated Product Folder Links: TMP4719 |
