7493 as a "divide-by-10 counter"

Hello,

A lab question I am doing is asking to show how a 7493 binary counter can be used as a "divide-by 10 counter."

So I understand that CP0 can be used as an input for dividing by two ad CP1 can be used for divide by 8.

Furthermore, CP1 can be tied to the LSB output to get divide by 16....

I cant seem to wrap my head around getting divide by 10, and Data sheet didn't help me.....

Thanks,

EDIT:

This will be a mod 10 counter so the 7493 should be reset at binary 9 count. to do this would "ANDing" the LSB and MSB together and then connecting to both master reset inputs work?

Can't you make use of RO(1) and Ro(2) to reset the counter to zero when it reaches '1010'?

I'll try it out on my sim.

Yes, of course, for the 74LS93 count of 0-9, reset to 0 when the count reaches 10 (Dec), A (HEX), 1010 (Bin).

So you have to reset to zero when you get to the account you want (MOD) +1.

with a 2-input AND gate can accomplish that.
