Built-in Functions
upper byte affects the time.
Returns:
Function:
undefined
This function will create code to perform a delay of the specified length. Time is
specified in milliseconds. This function works by executing a precise number of
instructions to cause the requested delay. It does not use any timers. If interrupts
are enabled the time spent in an interrupt routine is not counted toward the time.
The delay time may be longer than requested if an interrupt is serviced during the
delay. The time spent in the ISR does not count toward the delay time.

delay_us( )
Syntax:
delay_us ( time )
Parameters: time - a variable 0-65535(int16) or a constant 0-65535
Note: Previous compiler versions ignored the upper byte of an int16, now the upper
byte affects the time.
Returns:
Function:
undefined
Creates code to perform a delay of the specified length. Time is specified in
microseconds. Shorter delays will be INLINE code and longer delays and variable
delays are calls to a function. This function works by executing a precise number of
instructions to cause the requested delay. It does not use any timers. If interrupts
are enabled the time spent in an interrupt routine is not counted toward the time.
