the transmit cycle. Data is transmitted MSB first. To load data to
the DAC, PC7 is left low after the first eight bits are transferred,
and a second serial write operation is performed to the DAC.
PC7 is taken high at the end of this procedure.

If the user wants to verify the data previously written to the
input shift register, the SDO line can be connected to MISO of
the MC68HC11, and, with SYNC low, the shift register clocks
data out on the rising edges of SCLK.
MICROWIRE to AD5415 Interface
Figure 45 shows an interface between the DAC and any
MICROWIRE-compatible device. Serial data is shifted out on
the falling edge of the serial clock, SK, and is clocked into the
DAC input shift register on the rising edge of SK, which
corresponds to the falling edge of the DAC’s SCLK.

PIC16C6x/7x to AD5415 Interface
The PIC16C6x/7x synchronous serial port (SSP) is configured
as an SPI master with the clock polarity bit (CKP) = 0. This is
done by writing to the synchronous serial port control register
(SSPCON); see the
PIC16/17 Microcontroller User Manual
. In
this example, I/O port RA1 is used to provide a SYNC signal
and enable the serial port of the DAC. This microcontroller
transfers only eight bits of data during each serial transfer
operation; therefore, two consecutive write operations are
required. Figure 46 shows the connection diagram.
