1. 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 (0x42) to indicate fan failure. Setting the Configuration Register 1 (0x40) Lock bit has no effect on these
registers.

Description
When Bit 6 of Configuration 2 Register (0x73) is set (single-channel ADC mode), these bits
are reserved. Otherwise, these bits represent Bits [3:0] of the TACH1 minimum high byte.
When Bit 6 of Configuration 2 Register (0x73) is set (single-channel ADC mode), these bits
are used to select the only channel from which the ADC will take measurements. Otherwise,
these bits represent Bits [7:4] of the TACH1 minimum high byte.

1. These registers become read-only when the Configuration Register 1 (0x40) Lock bit is set to 1. Any subsequent attempts to write to these
registers fail.
