Bit 1 - COMP - configures the device to perform a comparison for the Hotter of Two mode (see

Bit 0 - REC - controls the Resistance Error Correction circuitry
The One Shot Register is an address place holder for the one-shot command. Writing to the address
initiates the command. The data written is not important and is not stored. Reading from the one-shot
registers will always return 00h.
The Ideality Configuration Registers store the ideality correction factor that is applied to each external
diode.
The table below shows the ideality factor settings for the Ideality Configuration registers. Shading
indicates power-up default. All codes that are not listed are reserved and should not be used.
Beta Compensation and Resistance Error Correction automatically correct for most diode ideality
errors, therefore it is not recommended that these settings be updated without consulting SMSC.
One Shot Register - (0Fh)
Ideality Configuration Registers (27h - 28h)
REGISTER
‘1’ - dynamic averaging is disabled. The ADC averaging factor will remain fixed at 1x for all
conversion rates and will allow increased power savings at the slower conversion rates.
‘0’ (default) - the device is in normal mode
‘1’ - the device is in Hotter of Two mode. In this mode, the two external diode channels are
measured and compared against each other. The hotter of the two channels has its data loaded
into the External Diode 2 Data Registers. The Internal Diode and External Diode 1 Data Registers
remain unaffected.
'0' (default)- The Resistance Error Correction circuitry is disabled.
'1' - The Resistance Error Correction circuitry is active and will automatically correct for up to 100
ohms of series resistance in the diode lines for the External Diode 2channel.
Writing to this register address initiates the one-shot. The data is not
important and is not stored
