FUNCTION
1
ALU busy bit. Set to 1 when the MAX11008 is performing internal
calculations. Set to 0 after calculations are complete.
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.
0
FIFO empty flag bit. Set to 1 when FIFO is empty. Set to 0 when data is
placed into the FIFO.
FIFO overflow/full flag bit. Set to 1 when in ADC monitoring mode and FIFO
0
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.
Channel 2 high current flag bit. Set to 1 when the channel 2 current-sense
0
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.
Channel 2 low current flag bit. Set to 1 when the channel 2 current-sense
0
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.
Channel 2 high temperature flag bit. Set to 1 when the channel 2
0
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.
Channel 2 low temperature flag bit. Set to 1 when the channel 2
0
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.
Channel 1 high current flag bit. Set to 1 when the channel 1 current-sense
0
measurement exceeds the channel 1 high current threshold and returns to
0 after the Flag register is read.
Channel 1 low current flag bit. Set to 1 when the channel 1 current-sense
0
measurement exceeds the channel 1 low current threshold and returns to 0
after the Flag register is read.
Channel 1 high temperature flag bit. Set to 1 when the channel 1
0
temperature measurement exceeds the channel 1 high temperature
threshold and returns to 0 after the Flag register is read.
Channel 1 low temperature flag bit. Set to 1 when the channel 1
0
temperature measurement exceeds the channel 1 low temperature
threshold and returns to 0 after the Flag register is read.
