CONVST. However, the SCLK line must be low when CONVST goes low in order to reset the output shift register correctly. The serial clock input does not have to be continuous during the serial read operation. The 16 bits of data (two leading zeros and 14-bit conversion result) can be read from the AD7894 in a number of bytes. The AD7894 counts the serial clock edges to know which bit from the output register should be placed on the SDATA out- put. To ensure that the part does not lose synchronization, the
