Status Register

The Status register is a read-only register that stores

the operational status of the part. When either TLOW or

THIGH are set (TA  low limit or TA > high limit) and the

ALERT/THERM2

not

masked,

the

ALERT/THERM2 pin will assert. See Section 4.3

“ALERT/THERM2 Output” for more details on the

ALERT function.

Each bit is cleared individually when the Status register

is read, provided that the error condition for that bit no

longer exists. The ALERT/THERM2 output is latched

and will not be reset until the host has responded with

an alert response address (ARA = 0001 100). The

ALERT/THERM2 output will not reset if the Status

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

RC = Read then Clear

bit 7

BUSY: ADC is busy converting a value

= ADC is converting

= ADC is not converting

bit 6

THIGH: Temperature High Limit bit

= Temperature High Limit is exceeded

= Temperature High Limit is within the limits

bit 5

TLOW: Temperature Low Limit bit

= Temperature Low Limit is exceeded

= Temperature Low Limit is within the limits

bit 3-1

Reserved: Unimplemented bit, read as ‘0’.

bit 0

THRM: THERM limit bit

= THERM limit is exceeded, ADDR/THERM output will be asserted

= THERM limit is in the limits
