AD5382
MICROPROCESSOR INTERFACING
Parallel Interface
The AD5382 can be interfaced to a variety of 16-bit microcon-
trollers or DSP processors. Figure 35 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
s
ignal 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 35.
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 (D
IN
)
of the AD5382, and the MISO input is driven from D
OUT
. The
SYNC signal is derived from a port line (PC7). When data is
Rev. 0 | Page 31 of 40
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.
