Lookup Table Temperature Entry 11
Bit 7 is unused and always set to 0 in the low resolution temperature LUT mode.
In the high resolution temperature LUT mode bit 7 in conjunction with bits 6:0 of
this register are used to determine the limit temperature that the remote diode
temperature is compared to. In high resolution the range is 0°C to 127.5°C. In
low resolution mode the range is 0°C to 127°C. If the remote diode temperature
exceeds this value, the PWM output will be the value in Register 0x65. Only 9-
bits of the temperature reading are used in high resolution and 8-bits in low
resolution. Only positive temperature values can be programed in this register
and in all cases the sign bit is assumed to be zero. Temperatures greater than
127 °C or 127.5 °C can be programmed through the use of the Lookup Table
Temperature Offset Register (4Eh).
Lookup Table PWM Duty Cycle Extended Entry 11
These bits are unused and always set to 0 in the low resolution duty cycle LUT
mode. In the high resolution duty cycle LUT mode these bits in association with
bits 5:0 of this register are used for the PWM value associated with the
temperature limit in register 0x64. These bits can only be activated when PWM
frequency of 22.5kHz is chosen.
Lookup Table PWM Duty Cycle Entry 11
The PWM value corresponding to the temperature limit in register 0x64 for the
low resolution PWM mode.

These bits are unused and always set to 0 in the low resolution duty cycle LUT
