Size — Size of FIFO, in bytes 1024 (default) | integer
Enter the number of elements that can be held in the FIFO at one time. If
a write operation to the FIFO causes the number of elements to exceed
Size, an error occurs.
Programmatic Use
Block Parameter:size
Input vector type — Specify input data type 8 bit uint null
terminated (default) | count+32 bit int | count+32 bit uint | count+16 bit int | count+16 bit uint | 8 bit int null terminated
For the 16-bit and 32-bit data types, include as first element the number
of elements to expect in the rest of the input vector. The count controls
how many bytes that the block copies into the FIFO. The block does not copy
the count itself into the FIFO.
For the 8-bit data types, provide a NULL-terminated character vector in
the output vector. The block copies data into the FIFO up to, but not
including, the NULL terminator.
Data present output — Enables output DP off (default) | on
Select this check box to create the Boolean output DP.
If data is present in the FIFO, DP becomes
true. The transmit side of the send/receive subsystem
uses this output. This output is given to the Enable TX block, which enables
the transmitter buffer empty interrupt.
This setting makes the output port DP visible.
Programmatic Use
Block Parameter:present
Sample time — Sample time of block -1 (default) | numeric
Enter the base sample time or a multiple of the base sample time. -1 means
that sample time is inherited.
Programmatic Use
sampletime
ID — Identifier for overflow messages character vector
Enter a user-defined identifier for FIFO overflow messages.
