Hottest Configuration Register
Channel Configuration Register
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 6 - 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.
Config
The Channel Configuration Register determines which external diode channels are active in the device.
Bit 7 - REM_HOT - Enables circuitry that will remember the last temperature channel that was
determined to be the Hottest and flag an error if the hottest temperature channel changes.
Bit 2 - EXT4_APD - Enables the DP4 / DN5 and DN4 / DP5 pins to support two anti-parallel diode
connections versus a single diode connection.
‘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.
‘0’ (default) - The HOTTEST status bit will not be asserted if the hottest temperature channel
changes.
‘1’ - If the hottest temperature channel changes, then the HOTTEST status bit will be asserted.
‘0’ (default) - The DP4 / DN5 and DN4 / DP5 pins do not support two anti-parallel diode
connections. The pins will only monitor a single external diode (External Diode 4).
‘1’ - The DP4 / DN5 and DN4 / DP5 pins support two anti-parallel diode connections (External
Diode 4 and External Diode 5).
