The TMU temperature calibration values are located here:

0x3035_04F0[7:0] TSENSOR_VALUE_RT[7:0] (room temp) Bank3 Word3 **Not in map
0x3035_04F0[15:8] TSENSOR_VALUE_HT[7:0] (high temp) Bank3 Word3 **Not in map

Q1. Can you please provide the bit definitions for the bits 31:16 at fuse location 0x3035_04F0[31:16]  TMU calibration values ?

0x3035_04F0[31:16] ???????????????????

From uboot prompt I do the following:

u-boot=> fuse read 3 3

Reading Bank 3

Word 0x00000003: 013c6636

Reading the shadow register at uboot prompt is:

u-boot=>md 0x303504f0 1

303504f0: 013c6636

Doing the bitfield decode

0x36=TE1 Room Temp 25'C calibration value

0x66=TE2 High Temp 85'C calibration value

In other words for the above values, what is the decode of 0x13c6 ?
