... MSB to LSB). 7 SCLK Digital Input. This is the microPort™ serial clock input. The TC3400 comes out of sleep mode and a conversion cycle begins when this pin is driven low. After the conversion starts, each additional falling edge (up to six) detected on SCLK for t conversion is complete, the data word can be shifted out on the SDAT pin by clocking the SCLK pin ...
