45 / 102 page ![]() 6.10.6 Configuration Register (Addresses 03h and 09h) Name: CONFIG Offset: 0x03, 0x09 Bit 7 6 5 4 3 2 1 0 MSKAL R/S AT/THM RECD1/2 RECD3/4 RANGE DA_ENA APDD Access RW RW RW RW RW RW RW RW Reset 0 0 0 0 0 0 0 0 Bit 7 – MSKAL Masks the ALERT pin from asserting when the ALERT pin is in Interrupt mode. This bit has no effect when the ALERT pin is in Comparator mode. Value Description 1 The ALERT pin is masked and will not be asserted for any interrupt condition when the ALERT pin is in Interrupt mode. The Status Registers will be updated normally. 0 The ALERT pin is not masked. If any of the appropriate Status bits are set, the ALERT pin will be asserted. Bit 6 – R/S Controls Run/Stop states. Value Description 1 The device is in Stop (standby) state and not converting (unless a one-shot has been commanded) 0 The device is in Run (active) state and converting on all channels Bit 5 – AT/THM Controls the operation of the ALERT pin. When the ALERT pin is in Comparator mode, each channel has a consecutive counter OR’ed to assert the ALERT pin. The ALERT pin is deasserted after one measurement is below the high limit minus the Therm Hysteresis. Value Description 1 The ALERT pin acts in Comparator mode as described in 5.5.2 ALERT/THERM2 Pin in Therm Mode. In this mode the MASK_ALL bit is ignored. 0 The ALERT pin acts in Interrupt mode as described in 5.5.1 ALERT/THERM2 Pin Interrupt Mode Bit 4 – RECD1/2 Disables the Resistance Error Correction (REC) for the DP1/DN1 pins. Value Description 1 REC is disabled for the DP1/DN1 and DP2/DN2 pins 0 REC is enabled for the DP1/DN1 and DP2/DN2 pins Bit 3 – RECD3/4 Disables the Resistance Error Correction (REC) for the DP2/DN2 pins. Value Description 1 REC is disabled for the DP2/DN2 and DP4/DN4 pins 0 REC is enabled for the DP2/DN2 and DP4/DN4 pins Bit 2 – RANGE Configures the measurement range and data format of the temperature channels.
