"When the user request delay which exceed the maximum possible one,
_delay_ms() provides a decreased resolution functionality. In this mode
_delay_ms() will work with a resolution of 1/10 ms, providing delays up
to 6.5535 seconds (independent from CPU frequency). The user will not be
informed about decreased resolution."
