Table 02h, Register ACh to ADh: Reserved
FACTORY DEFAULT:
READ ACCESS
WRITE ACCESS
MEMORY TYPE:
These registers are reserved.
Table 02h, Register AEh to AFh: Internal Temp Offset
FACTORY CALIBRATED
READ ACCESS
WRITE ACCESS
MEMORY TYPE
Allows for offset control of the temperature measurement if desired. The final result must be XORed with BB40h before writing to
this register. Factory calibration contains the desired value for a reading in degrees Celsius.
Table 02h, Register B0h to B3h: PW1
FACTORY DEFAULT
READ ACCESS
WRITE ACCESS
MEMORY TYPE
The PWE value is compared against the value written to this location to enable PW1 access. At power-on, the PWE value is set to all
ones. Thus, writing these bytes to all ones grants PW1 access on power-up without writing the password entry. All reads of this
register are 00h.
