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);

}
