98 Serial I/O Models
kbaud ( const-expr )
Specifies the bit rate for a Neurowire master. The expression const-expr can
evaluate to 1, 10, or 20. The default is 20. The firmware uses this value as a
multiplier based on the Series 3100 input clock or Series 5000 system clock.
For example, for a Series 3100 device at 10 MHz, kbaud(10) yields 10 kbps;
for a Series 5000 device at 10 MHz, kbaud(10) yields 20 kbps. The bit rate
scales proportionally with the input or system clock.
Not used for a Neurowire slave.
clockedge (+|-)
Specifies the polarity of the clock signal. The default is a rising edge clock,
clockedge (+). Specifying clockedge (-) causes the data to be clocked at the
falling edge of the clock signal.
io-object-name
A user-specified name for the I/O object, in the ANSI C format for variable
identifiers.
Usage
unsigned int count , io - buffer [ buffer - size ];
io_out( io - object - name , io - buffer , count );
Example
IO_8 neurowire master select(IO_2) ioDisplay;
IO_2 output bit ioDisplaySelect = 1; // active low
// 8 bits=>display config reg
unsigned int config = 0x01;
// 24 bits=>display data reg
unsigned int data[3];
when (...) {
io_out(ioDisplaySelect, 0);
config = 0x01;
io_out(ioDisplay, &config, 8);
data[0] = 0x80;
data[1] = 0xAB;
data[2] = 0xCD;
io_out(ioDisplay, data, 24);
io_out(ioDisplaySelect, 1);
}
SCI (UART) Input/Output
You can use the hardware Serial Communications Interface (SCI) I/O model in
applications that you develop for Smart Transceivers or Neuron Chips with
integrated universal asynchronous receiver/transmitter (UART) hardware such
as the PL 3120 Smart Transceiver, PL 3150 Smart Transceiver, PL 3170 Smart
Transceiver, or a Series 5000 device. SCI is an asynchronous serial
