______________________________________________________________________________________
The MAX1403 can be configured to sequentially scan
all signal inputs and to transmit the results through the
serial interface with minimum communications over-
head. The output word contains a channel identification
tag to indicate the source of each conversion result.
Serial Digital Interface
The serial digital interface provides access to eight on-
chip registers (Figure 3). All serial-interface commands
begin with a write to the communications register
(COMM). On power-up, system reset, or interface reset,
the part expects a write to its communications register.
The COMM register access begins with a 0 start bit.
The COMM register R/W bit selects a read or write
operation, and the register select bits (RS2, RS1, RS0)
select the register to be addressed. Hold DIN high
when not writing to COMM or another register (Table 1).
The serial interface consists of five signals: CS, SCLK,
DIN, DOUT, and INT. Clock pulses on SCLK shift bits
into DIN and out of DOUT. INT provides an indication
that data is available. CS is a device chip-select input
as well as a clock polarity select input (Figure 4).
Using CS allows the SCLK, DIN, and DOUT signals to
be shared among several SPI-compatible devices.
When short on I/O pins, connect CS low and operate
the serial digital interface in CPOL = 1, CPHA = 1 mode
using SCLK, DIN, and DOUT. This 3-wire interface mode
is ideal for opto-isolated applications. Furthermore, a
microcontroller (such as a PIC16C54 or 80C51) can
use a single bidirectional I/O pin for both sending to
DIN and receiving from DOUT (see Applications
Information), because the MAX1403 drives DOUT only
during a read cycle.
Additionally, connecting the INT signal to a hardware
interrupt allows faster throughput and reliable, collision-
free data flow.
The MAX1403 features a mode where the raw modula-
tor data output is accessible. In this mode, the DOUT
and INT functions are reassigned (see the Modulator
Data Output section).
