8-bit Scratchpad data to store user-programmable data.

Reading the register returns the previously programmed

content. The data is volatile and power needs to be supplied

to the device for the programmed data to be retained.

8.14 THigh_Limit_Remote_Ch1_Low Register (Address = 13h) [reset = 00h]

This register is used to configure the low byte (bits 3:0) of the temperature high limit for remote channel 1.

THigh_Limit_Remote_Ch1_Low[3:0] R/W

Low-byte (bits 3:0) of the 12-bit temperature alert high limit

setting for remote channel 1.

Use the THigh_Limit_Remote_Ch1_High register together with

the THigh_Limit_Remote_Ch1_Low register to get the full 12-bit

temperature alert high limit for remote channel 1.
