Bits Name Description
Hex Write Value
7 0 E2T7 Lookup Table Temperature Entry 2
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
52
exceeds this value, the PWM output will be the value in Register 0x53. Only 9-bits
6:0 0x7F E2T6:E2T0
of the temperature reading are used in high resolution and 8-bits in low resolution.
Read.
Only positive temperature values can be programed in this register and in all cases
(Write
the sign bit is assumed to be zero. Temperatures greater than 127 °C or 127.5 °C
only if
can be programmed through the use of the Lookup Table Temperature Offset
reg 4A
Register (4Eh).
bit 5 =
Lookup Table PWM Duty Cycle Extended Entry 2
1)
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
7:6 00 E2D7:E2D6
bits 5:0 of this register are used for the PWM value associated with the
temperature limit in register 0x52. These bits can only be activated when PWM
53
frequency of 22.5kHz is chosen.
Lookup Table PWM Duty Cycle Entry 2
5:0 0x3F E2D5:E2D0 The PWM value corresponding to the temperature limit in register 0x52 for the low
resolution PWM mode.
7 0 E3T7 Lookup Table Temperature Entry 3
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
54
exceeds this value, the PWM output will be the value in Register 0x55. Only 9-bits
6:0 0x7F E3T6:E3T0
of the temperature reading are used in high resolution and 8-bits in low resolution.

resolution mode the range is 0°C to 127°C. If the remote diode temperature
56
exceeds this value, the PWM output will be the value in Register 0x57. Only 9-bits
