DATA BITS BIT NAME RESET STATE FUNCTION
D[15:12] Reserved X Reserved bits.
D11 ALUBUSY 1
ALU busy bit. Set to 1 when the MAX11008 is performing internal
calculations. Set to 0 after calculations are complete.
D10 RESTART 0
Restart flag bit. Set to 1 after a full software reset is performed. Returns to 0
after the Flag register is read. Set to 0 after initial power-up.
D9 FIFOEMP 0
FIFO empty flag bit. Set to 1 when FIFO is empty. Set to 0 when data is
placed into the FIFO.
D8 FIFOOVER 0
FIFO overflow/full flag bit. Set to 1 when in ADC monitoring mode and FIFO
overflow occurs. Returns to 0 when after Flag register is read. Set to 1 when
in LUT streaming mode and the FIFO is full. Returns to 0 after a data word
is moved out of the FIFO.
D7 HIGHI2 0
Channel 2 high current flag bit. Set to 1 when the channel 2 current-sense
measurement exceeds the channel 2 high current threshold and returns to
0 after the Flag register is read. When the INTEMP2 bit is set, this bit
functions as the internal temperature sensor’s alarm status.
D6 LOWI2 0
Channel 2 low current flag bit. Set to 1 when the channel 2 current-sense
measurement exceeds the channel 2 low current threshold and returns to 0
after the Flag register is read. When the INTEMP2 bit is set, this bit
functions as the internal temperature sensor’s alarm status.
D5 HIGHT2 0
Channel 2 high temperature flag bit. Set to 1 when the channel 2
temperature measurement exceeds the channel 2 high temperature
threshold and returns to 0 after the Flag register is read. When the
INTEMP2 bit is set, this bit is unused and may read as 1 or 0.
D4 LOWT2 0
Channel 2 low temperature flag bit. Set to 1 when the channel 2
temperature measurement exceeds the channel 2 low temperature
threshold and returns to 0 after the Flag register is read. When the
INTEMP2 bit is set, this bit is unused and may read as a 1 or 0.
D3 HIGHI1 0
Channel 1 high current flag bit. Set to 1 when the channel 1 current-sense
measurement exceeds the channel 1 high current threshold and returns to
0 after the Flag register is read.
D2 LOWI1 0
Channel 1 low current flag bit. Set to 1 when the channel 1 current-sense
measurement exceeds the channel 1 low current threshold and returns to 0
after the Flag register is read.
D1 HIGHT1 0
Channel 1 high temperature flag bit. Set to 1 when the channel 1
temperature measurement exceeds the channel 1 high temperature
threshold and returns to 0 after the Flag register is read.
D0 LOWT1 0
Channel 1 low temperature flag bit. Set to 1 when the channel 1
temperature measurement exceeds the channel 1 low temperature
threshold and returns to 0 after the Flag register is read.
