The first falling edge of SYNC resets a counter that counts the number of serial clocks, ensuring the correct number of bits are shifted in and out of the serial shift registers. A rising edge on SYNC during a write causes the write cycle to be aborted. After the falling edge of the 16th SCLK pulse, data is auto- matically transferred from the input shift register to the DAC. For another serial transfer to take place, the counter must be reset by the falling edge of SYNC. |
