The TMP411-Q1 and TMP411D-Q1 stores the minimum and maximum temperature measured since power on, chip reset, or minimum and maximum register reset for both the local and remote channels. The Local Temperature Minimum Register is read with the high byte from pointer address 30h, and the low byte is read from pointer address 31h. The Local Temperature Minimum Register is read with a two-byte read command from pointer address 30h. The Local Temperature Minimum Register resets at power-on by executing the chip-reset command, or by writing any value to any of the pointer addresses 30h through 37h. The reset value for these registers is FFh/F0h.

The Local Temperature Maximum Register is read with the high byte from pointer address 32h and the low byte from pointer address 33h. The Local Temperature Maximum Register is read with a two-byte read command from pointer address 32h. The Local Temperature Maximum Register resets at power-on by executing the chip reset command, or by writing any value to any of the pointer addresses 30h through 37h. The reset value for these registers is 00h/00h.

The Remote Temperature Minimum Register is read with the high byte from pointer address 34h and the low byte from pointer address 35h. The Remote Temperature Minimum Register is read with a two-byte read command from pointer address 34h. The Remote Temperature Minimum Register resets at power-on by executing the chip reset command, or by writing any value to any of the pointer addresses 30h through 37h. The reset value for these registers is FFh/F0h.

The Remote Temperature Maximum Register is read with the high byte from pointer address 36h and the low byte from pointer address 37h. The Remote Temperature Maximum Register is read with a two-byte read command from pointer address 36h. The Remote Temperature Maximum Register resets at power-on by executing the chip reset command, or by writing any value to any of the pointer addresses 30h through 37h. The reset value for these registers is 00h/00h.
