Serial Digital Output
DIO is configured as a digital output by writing a Read
IRS (RDIRS) command (5 hex) to the CRIL location. On
receipt of this command, the MAX1455 outputs a byte
of data, the contents of which are determined by the
IRS pointer (IRSP[3:0]) value at location IRSA[3:0] =
8hex. The data is output as a single byte, framed by a
start bit and a stop bit. Table 11 lists the data returned
for each IRSP address value.
Once the RDIRS command has been sent, all connec-
tions to DIO must be three-stated to allow the MAX1455
to drive the DIO line. Following receipt of the RDIRS
command, the MAX1455 drives DIO high after 1 byte
time. The MAX1455 holds DIO high for a single bit time
and then asserts a start bit (drives DIO low). The start
bit is then followed by the data byte and a stop bit.
Immediately following transmission of the stop bit, the
MAX1455 three-states DIO, releasing the line. The
MAX1455 is then ready to receive the next command
sequence 1 byte time after release of DIO.
Note that there are time intervals before and after the
MAX1455 sends the data byte when all devices on the
DIO line are three-stated. It is recommended that a
weak pullup resistor be applied to the DIO line during
these time intervals to prevent unwanted transitions
(Figure 4). In applications where DIO and analog out-
be permanently connected to DIO. If the MAX1455 DIO
and analog outputs are connected, then do not load
this common line during analog measurements. In this
situation, perform the following sequence:
1) Connect a pullup resistor to the DIO/OUT line,
preferably with a relay.
2) Send the RDIRS command.
3) Three-state the user connection (set to high imped-
ance).
4) Receive data from the MAX1455.
5) Activate the user connection (pull DIO/OUT line high).
6) Release the pullup resistor.
