Hi!
When trying to measure the temperature with the MAX1617A sensor at high temperatures (+120 degrees), by gradually increasing the heat, the external REMOTE sensor reaches a temperature of about 110 degrees and makes a jump to the maximum value of +127, resulting in a temperature value of 0111_1111 in the temperature value register. During debugging, the following actions were performed:
1) When checking the RSL status registers, the OPEN flag is detected as zero, as it should be when the external transistor is connected. But when the temperature is displayed as +127, the RHIGH flag is set to 1 (while the ambient temperature is less than 127 degrees)
2) When the external sensor is gradually heated to 125 degrees at a temperature of about 110 degrees, the displayed temperature jumps to 127 degrees and an ALERT is triggered, caused by the upper temperature limit, which is set to a maximum of 127 degrees by default and programmatically.
