Echelon Neuron C - Manual (Page 156)

136 Functions
void sleep (unsigned int flags , io-object-name );
void sleep (unsigned int flags , io-pin );
flags One or more of the following three flags, or 0 if no flag is
specified:
COMM_IGNORE Causes incoming messages to be
ignored
PULLUPS_ON Enables all I/O pullup resistors
(the service pin pullup is not
affected)
TIMERS_OFF Turns off all timers in the
program
If two or more flags are used, they must be combined
using either the + or the | operator.
io-object-name Specifies an input object for any of the IO_4 through IO_7
pins. When any I/O transition occurs on the specified pin,
the Neuron core wakes up. If neither this parameter nor
the
io-pin argument are specified, I/O is ignored after the
Neuron core goes to sleep.
io-pin Specifies one of the IO_4 through IO_7 pins directly
instead of through a declared I/O object.
Example
IO_6 input bit wakeup;
...
when (flush_completes)
{
sleep(COMM_IGNORE + TIMERS_OFF, wakeup);
}
spi_abort( ) Function
The spi_abort( ) built-in function terminates any outstanding SPI I/O operation
in progress.
Syntax
void spi_abort ( io-object-name );
Example
IO_8 spi master clock(4) iospi;
when (...)
{
spi_abort(iospi);
}
