MICROPROCESSOR INTERFACING
Parallel Interface
The AD5382 can be interfaced to a variety of 16-bit microcon-
trollers or DSP processors. Figure 34 shows the AD5382 family
interfaced to a generic 16-bit microcontroller/DSP processor.
The lower address lines from the processor are connected to
A0–A4 on the AD5382. The upper address lines are decoded
to provide a CS, LDAC signal for the AD5382. The fast interface
timing of the AD5382 allows direct interface to a wide variety
of microcontrollers and DSPs, as shown in Figure 34.
AD5382 to MC68HC11
The serial peripheral interface (SPI) on the MC68HC11 is
configured for master mode (MSTR = 1), Clock Polarity bit
(CPOL) = 0, and the Clock Phase bit (CPHA) = 1. The SPI is
configured by writing to the SPI control register (SPCR)—see
the 68HC11 User Manual. SCK of the 68HC11 drives the
SCLK of the AD5382, the MOSI output drives the serial data
line (DIN) of the AD5382, and the MISO input is driven from
DOUT. The SYNC signal is derived from a port line (PC7).
When data is being transmitted to the AD5382, the SYNC line
is taken low (PC7). Data appearing on the MOSI output is valid
on the falling edge of SCK. Serial data from the 68HC11 is
transmitted in 8-bit bytes with only eight falling clock edges
occurring in the transmit cycle.
