17 / 24 page ![]() AD5662 Rev. A | Page 17 of 24 AD5662 to 80C51/80L51 Interface AD5662 to MICROWIRE Interface Figure 39 shows a serial interface between the AD5662 and the 80C51/80L51 microcontroller. The setup for the interface is as follows. TxD of the 80C51/80L51 drives SCLK of the AD5662, while RxD drives the serial data line of the part. The SYNC signal is again derived from a bit-programmable pin on the port. In this case, port line P3.3 is used. When data is to be transmitted to the AD5662, P3.3 is taken low. The 80C51/80L51 transmits data in 8-bit bytes only; thus only eight falling clock edges occur in the transmit cycle. To load data to the DAC, P3.3 is left low after the first eight bits are transmitted, and a second write cycle is initiated to transmit the second byte of data. P3.3 is taken high following the completion of this cycle. The 80C51/80L51 outputs the serial data in a format that has the LSB first. The AD5662 must receive data with the MSB first. The 80C51/80L51 transmit routine should take this into account. Figure 40 shows an interface between the AD5662 and any MICROWIRE-compatible device. Serial data is shifted out on the falling edge of the serial clock and is clocked into the AD5662 on the rising edge of the SK.
