procedure Delay_ms(time_in_ms: const longword);

Nothing.

Creates a software delay in duration of time_in_ms milliseconds (a constant).
Range of applicable constants depends on the oscillator frequency.

This is an “inline” routine; code is generated in the place of the call, so the call
doesn’t count against the nested call limit.

Nothing.

Delay_ms(1000);  // One second pause 

procedure Vdelay_ms(time_in_ms: word);

Nothing.

Creates a software delay in duration of time_in_ms milliseconds (a variable).
Generated delay is not as precise as the delay created by Delay_ms.

Note that Vdelay_ms is library function rather than a built-in routine; it is pre-
sented in this topic for the sake of convenience.

Nothing.

pause := 1000;

// ...
Vdelay_ms(pause);  // ~ one second pause

procedure Delay_Cyc(Cycles_div_by_10: byte);

Nothing.

Creates a delay based on MCU clock. Delay lasts for 10 times the input param-
eter in MCU cycles.

Note that Delay_Cyc is library function rather than a built-in routine; it is pre-
sented in this topic for the sake of convenience. There are limitations for
Cycles_div_by_10 value. Value Cycles_div_by_10 must be between 2 and 257.

Nothing.

Delay_Cyc(10);  // Hundred MCU cycles pause
