Data Sheet

MICROWIRE to AD5425 Interface

Figure 43 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 SCLK.

PIC16C6x/PIC16C7x to AD5425

The PIC16C6x/PIC16C7x (Microchip) 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). In this example, RA1 input/output

port provides a SYNC signal and enable the DAC serial port. This

microcontroller transfers eight bits of data during each serial

transfer operation. Figure 44 shows the connection diagram.
