Creating 1uS delay

[Ron]

Hi,

I want to create a 1uS delay while running at 19.6608MHz.

I know I how to use delay_10us(1); and I think there is delay_100us(1);.

I do not think there is a 1us delay function.

How do I calculate how long an instruction takes to execute?

I imagine NOP can be used so please start with this.

How many NOP statements are required for 1us delay?

Can you provide example with different commands that take up different number of clock cycles please.

How/where can I find out how many cycles each command takes?


Thank you,

Ron

Hi Ron,
You can try

Code: Select all

delay_us(1);
