Approximates a 1 millisecond delay using "nop". This is less
|
||
|
|
accurate than a dedicated timer, but is useful in certain situations.
|
||
|
|
|
||
|
|
The number of ticks to delay depends on the optimisation level set
|
||
|
|
when compiling (-O). Depending on the compiler settings, one of the
|
||
|
|
two defined values for 'delay' should be used.
