Power-Down Timer Register Bit Map Bit Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Mnemonic – – Power-Down Timeout (6-Bit Value) Default 0 0 0x00 Table 15.Power-Down Timer Register Bit Descriptions Bit Mnemonic Description [7:6] – These bits must be 0 for proper operation. [5:0] Power-Down Timeout Defines period duration of the power-down timeout. If the output comparator outputs have not been activated during the programmed period, the part enters power-down mode automatically. The part can be then returned to a normal operational mode either via the serial interface or by the power supply off/on sequence. The period is programmable in steps of four hours. For example, setting the value to 0x06 sets the duration to 24 hours. The maximum value of 0x3F corresponds to approximately 10.5 days. The value of 0x00 disables the power-down timeout, and the part does not enter power-down mode automatically. CAPDAC REGISTERS Ch1 Address Pointer 0x11 Ch2 Address Pointer 0x12 8 Bits, Read/Write, Factory Preset 0x00 Table 16. CAPDAC Registers Bit Map Bit Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Mnemonic DacEn DacAuto DacValue (6-Bit Value) Default 1 1 0x00 Table 17. CAPDAC Registers Bit Descriptions Bit Mnemonic Description 7 DacEn DacEn = 1 enables capacitive DAC. 6 DacAuto DacAuto = 1 enables the AutoDAC function in the adaptive threshold mode. When the AutoDAC function is enabled, the part dynamically adjusts the CAPDAC to keep the CDC in an optimal operating capacitive range. The CAPDAC value is automatically incremented when the data average exceeds ¾ of the CDC full range, and the CAPDAC value is decremented when the data average goes below ¼ of the CDC full range. The AutoDAC increment or decrement step depends on the selected CDC capacitive input range. Bit has no effect in fixed threshold mode; the AutoDAC function is always disabled in the fixed threshold mode. [5:0] DacValue CAPDAC value, Code 0x00 ≈ 0 pF, Code 0x3F ≈ CAPDAC full range. SERIAL NUMBER REGISTER Address Pointer 0x13, 0x14, 0x15, 0x16 32 Bits, Read-Only, 0xXXXX This register holds a serial number, unique for each individual part. CHIP ID REGISTER Address Pointer 0x17 8 Bits, Read-Only, 0xXX This register holds the chip identification code, used in factory manufacturing and testing. |
