MT8880 clock pulses missing?

Hi

I found this code and try to understand it ,according to the datasheet.

I fail to find the clock pulses in the code, if it is somehow implemented please show me where.

I hope the above link is usable looks as if it is duplicated twice.

Thanks in advance.

Mike.

maybe this code here might help you (it looks more comprehensive than the one you posted!)

hope that helps.

Thanks.

 if (which & LEFT) digitalWrite(LEFT_CS_PIN, HIGH); 
 if (which & RIGHT) digitalWrite(RIGHT_CS_PIN, HIGH);

This is even worse , 2 CS lines ?? 2 MT8880 chips ???

I did write .ASM code for the MT8880 for a PIC 16F876 many years back ,so I want to duplicate that project in C with Arduino.
