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: 0 = WDT pin at logic ‘0’; 1 = WDT pin at logic ‘1’
x = 1..12 0 = turn off shorting switch for cell ‘x’ (default); 1 = turn on shorting switch
Comparison voltage = (VUV – 31) • 16 • 1.5mV
Comparison voltage = (VOV – 32) • 16 • 1.5mV
Read: 0 = test passed; 1 = test failed
