AD5381 to PIC16C6x/7x
The PIC16C6x/7x synchronous serial port (SSP)is configured
as an SPI master with the ClockPolarity Bit = 0. This is done
by writing to the synchronousserial port control register
(SSPCON). See the PIC16/17 microcontroller user manual.
In this example I/O, Port RA1 is being used to pulse SYNC
and enable the serial port of the AD5381. This microcontroller
transfers only eight bits of dataduring each serial transfer
operation; therefore,threeconsecutiveread/write operations
may be needed depending on the mode. Figure 36 showsthe
connection diagram.

AD5381 to 8051
The AD5381 requires a clocksynchronized to the serial data.
The 8051 serial interface must thereforebe operated in Mode 0.
In this mode, serial data enters and exits through RxD, and a
shift clock is output on TxD. Figure 37 shows howthe 8051 is
connected to the AD5381. Because the AD5381 shifts data out
on the rising edge of the shift clock and latches data in on the
falling edge, the shift clock must be inverted.The AD5381
requires its data to be MSBfirst. Since the 8051 outputs the
LSB first, the transmit routine must take this into account.

AD5381 to ADSP-2101/ADSP-2103
Figure 38 shows a serial interface between the AD5381 and the
ADSP-2101/ADSP-2103. The ADSP-2101/ADSP-2103 should
be set up to operate in SPORT transmit alternateframing mode.
The ADSP-2101/ADSP-2103 SPORT is programmedthrough
the SPORT control registerand configuredas follows: internal
clock operation,active low framing, and 16-bit word length.
Transmission is initiated by writing a word to the Tx register
after the SPORT has been enabled.
