REC Configuration Register
Hottest Configuration Register
Bit 2 - E2THERM - This bit is set when the External Diode 2 channel meets or exceeds it’s
programmed THERM Limit.
Bit 1 - E1THERM - This bit is set when the External Diode 1 channel meets or exceeds it’s
programmed THERM limit.
Bit 0- ITHERM - This bit is set when the Internal Diode channel meets or exceeds it’s programmed
THERM limit.
The REC Control Register controls the Resistance Error Correction circuitry for each of the external
diode channels.
Bits 7 -0- EX_REC_n - Disables the Resistance Error Correction (REC) for the External Diode X
channel.
The Hottest Configuration Register determines which External Diode Channels (if any) are compared
during the “Hottest Of” comparison that is automatically performed at the end of every conversion
cycle.
Bits 7 - 0 - ExHOT - Controls whether the External Diode X temperature data is compared during the
“Hottest Of” comparison.
Bit 0 - IHOT - Controls whether the Internal Diode temperature data is compared during the “Hottest
Of” comparison.
‘0’ (default) - REC is enabled.
‘1’ - REC is disabled.
‘0’ (default) - The External Diode X channel is not compared during the “Hottest Of” Comparison.
‘1’ - The External Diode X channel temperature data is compared to all other indicated channels
during the “Hottest Of” Comparison.
‘0’ (default) - The Internal Diode channel is not compared during the “Hottest Of” Comparison.
‘1’ - The Internal Diode channel temperature data is compared to all other indicated channels during
the “Hottest Of” Comparison.
