20 / 24 page bipolar mode, or set the lower threshold to 0x000 and the upper threshold to 0xFFF for unipolar mode. Readback Mode Select readback mode by setting CS3, CS2 to [1,1] in the configuration byte. Begin a read operation to start reading back monitor-setup data. Clock out delay bit settings, INT_EN bit, and the lower and upper thresh- olds programmed for each channel. Readback mode follows exactly the same format as writing to the moni- tor-setup data, with the exception of the first 4 alarm- reset bits, which are always 1 (Table 13). Reading in Monitor Mode Reading in monitor mode reads back the alarm-status register, latched-fault register, and current-conversion results as shown in Table 14. The MAX1363/MAX1364 register pointer loops back to the beginning of the current-conversion result after reading the last conversion result. Stop reading at any time by asserting a STOP condition or NACK. Note: The MAX1363/MAX1364 do not update the cur- rent-conversion results register while reading in monitor mode. Monitor mode resumes after a STOP condition or NACK. Alarm-Status Register and Latched-Fault Register The latched-fault register records a snapshot of the alarming channel at the instance that a fault condition is asserted. An alarm-status bit of 1 (Table 15) indicates a fault, and the data in the latched-fault register of the corresponding channel contains the conversion result that caused the alarm to trip. Resetting alarms does not clear the latched-fault register, thus the latched-fault register contains valid data only if an alarm status bit is high for the given channel. The current-conversion register contains the most recent conversion results. If the user attempts to read past the last result of the current-conversion register, the MAX1363/MAX1364 wraps back to the beginning of the current-conversion result. The latched-fault register and current-conversion regis- ter follow the data format in the Reading a Conversion (Read Cycle) section. Register length depends on the number of conversions in one monitoring sequence. For example, when channel pairs 0/1 and channels 2/3 are monitored differentially, there are only two conversion results to report. The latched-fault register is 2 x 16 bits long, after which two current-conversion results follow. Likewise, if CS0 and CS1 limit the upper bound of the channel scan range from CH0 to CH2 in single-ended mode, the latched-fault register clocks out 3 x 16 bits of data followed by the current-conversion results, also 3 x 16 bits. 4-Channel, 12-Bit System Monitors with Programmable Trip Window and SMBus Alert Response 20 ______________________________________________________________________________________ ALARM RESET/SCAN SPEED AIN0 THRESHOLDS AIN1 THRESHOLDS (SKIP IF DIFFERENTIAL MODE OR CS1, CS0 < 1) AIN2 THRESHOLDS (SKIP IF CS1, CS0 < 2) AIN3 THRESHOLDS (SKIP IF DIFFERENTIAL MODE OR CS1, CS0 < 3) 1 1 1 1 D2 D1 D0 INT 24 bits 24 bits 24 bits 24 bits Table 13.
