Exceeding any of these temperature limits by 1°C causes the appropriate status bit to be set in the interrupt status register. Setting the Configuration Register 1 lock
bit has no effect on these registers.
High Limits: An interrupt is generated when a value exceeds its high limit (> comparison). Low Limits: An interrupt is generated when a value is equal to or below its
low limit ( ≤ comparison).

Exceeding any of the TACH limit registers by 1 indicates that the fan is running too slowly or has stalled. The appropriate status bit is set in Interrupt Status Register 2
to indicate the fan failure. Setting the Configuration Register 1 lock bit has no effect on these registers.

Description
These bits are reserved when Bit 6 of Configuration 2 Register (0x73) is set (single-channel ADC mode).
Otherwise, these bits represent Bits <4:0> of the TACH1 minimum high byte.
<7:5>
SCADC
Read/write
When Bit 6 of Config 2 Register (0x73) is set (single channel ADC mode), these bits are used to select the
only channel from which the ADC makes measurements. Otherwise, these bits represent Bits <7:5> of
the TACH1 minimum high byte.
