VALUES
*when MMB pin is low, the CDC value is set to 5
0=12-cell mode (default); 1=10-cell mode
0=toggle polling (default); 1=level polling
Write: 0=GPIO1 pin pull down on; 1=GPIO1 pin pull down off (default)
Read: 0=GPIO1 pin at logic ‘0’; 1=GPIO1 pin at logic ‘1’
Write: 0=GPIO2 pin pull down on; 1=GPIO2 pin pull down off (default)
Read: 0=GPIO2 pin at logic ‘0’; 1=GPIO2 pin at logic ‘1’
Read Only: 0=WDTB pin at logic ‘0’; 1=WDTB pin at logic ‘1’
x=1..12
Comparison voltage = VUV * 16 * 1.5mV
(default VUV=0. When MMB pin is low a factory programmed comparison voltage is used)
Comparison voltage = VOV * 16 * 1.5mV
(default VOV=0. When MMB pin is low a factory programmed comparison voltage is used)
x=1..12
x=1..12
x=1..12
x=1..12
Temperature measurement voltage = ETMPx * 1.5mV
0= thermal shutdown has not occurred; 1=thermal shutdown has occurred
Status cleared to ‘0’ on read of Thermal Register Group
Device revision code
Temperature measurement voltage = ITMP * 1.5mV = 8mV * T(°K)

0=turn off shorting switch for cell ‘x’ (default); 1=turn on shorting switch
0=enable interrupts for cell ‘x’ (default)
1=turn off interrupts and clear flags for cell ‘x’
12-bit ADC measurement value for cell ‘x’
cell voltage for cell ‘x’ = CxV * 1.5mV
reads as 0xFFF while A/D conversion in progress
cell voltage compared to VUV comparison voltage
0=cell ‘x’ not flagged for under voltage condition; 1=cell ‘x’ flagged
