Bits Name Description
Hex Write Value
7 0 E5T7 Lookup Table Temperature Entry 5
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
58
exceeds this value, the PWM output will be the value in Register 0x59. Only 9-bits
6:0 0x7F E5T6:E5T0
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 5
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 E5D7:E5D6
bits 5:0 of this register are used for the PWM value associated with the
temperature limit in register 0x58. These bits can only be activated when PWM
59
frequency of 22.5kHz is chosen.
Lookup Table PWM Duty Cycle Entry 5
5:0 0x3F E5D5:E5D0 The PWM value corresponding to the temperature limit in register 0x58 for the low
resolution PWM mode.
7 0 E6T7 Lookup Table Temperature Entry 6
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
5A
exceeds this value, the PWM output will be the value in Register 0x5B. Only 9-bits
6:0 0x7F E6T6:E6T0
of the temperature reading are used in high resolution and 8-bits in low resolution.
