8 / 8 page AD7233 REV. A –8– AD7233-68HC11 Interface Figure 8 shows a serial interface between the AD7233 and the 68HC11 microcontroller. SCK of the 68HC11 drives SCLK of the AD7233 while the MOSI output drives the serial data line. The SYNC signal is derived from a port line (PC7 shown). For correct operation of this interface, the 68HC11 should be configured such that its CPOL bit is a 0 and its CPHA bit is a 1. When data is to be transmitted to the part, PC7 is taken low. When the 68HC11 is configured like this, data on MOSI is valid on the falling edge of SCK. The 68HC11 transmits its se- rial data in 8-bit bytes with only eight falling clock edges occur- ring in the transmit cycle. To load data to the AD7233, PC7 is kept low after the first eight bits are transferred and a second byte of data is then transferred serially to the AD7233. When the second serial transfer is complete, the PC7 line is taken high. Figure 8 shows the LDAC input of the AD7233 hard- wired low. As a result, the DAC latch and the analog output of the DAC will be updated on the sixteenth falling edge of SCK after the respective SYNC signal has gone low. Alternatively, the scheme used in previous interfaces, whereby the LDAC in- put is driven from a timer, can be used.
