Remote 2 Status Register
The Remote 2 Status register is a read only register that stores the operational status of the remote 2
temperature.

Bits 2 and 1 indicate that the Remote 2 temperature is above or below its high or low limits. See
Section 4.13, "Limit Registers," on page 17 for detail on the limits are compared. Bits 0 indicates that
the Remote 2 temperature has exceeded its THERM limit. If bit 0 goes high the ADDR/THERM signal
will be asserted.
Bits 2 and 1 will be cleared individually when the status register is read provided that the error condition
for that bit is gone.

Bit 7 is used to mask the ALERT/THERM2 output. When this bit is set to 0, any out of limit condition
will assert ALERT/THERM2. This bit is ignored if the ALERT/THERM2 pin is configured as THERM2 signal
by bit 5.
