Clock signal is a particular type of signal that oscillates
between a high and a low state and is utilized like a metronome
to coordinate actions of digital circuits. Any circuit which is
can generate repetitive signal without any input can be termed
an oscillator. A crystal is an oscillator which can create an
electrical signal with a precise frequency. Since it has a
precise frequency it also possess high stability in creating
frequency. The frequency it produce doesn’t drift with aging.
Crystal is used as a clock source most of the times.

base sa lecture dati , T= 1/2 , T= 1/11.0592 MHz

Actually you cant convert frequency into hex since it don't have
any relationship and connection. But you can just compute for
the t (t=1/f). You can use the T states computation. This will
be useful in delay computation.

can you teach me how or just give me an idea. Thank you so
much. :)

You can use this picture above as a reference for outputting
letters. We use latch since it enable us to give two or more
output. For example I have a 2 7-segment (S1 and S2) and i want
to output number 0(#3F) and 1(#06). The pin where we enable S1
is in P3.1 and the enabling pin in S2 is in P3.2. The program
should be look like this.
[center]
MOV P1 #3F
SET P3.1
CLR P3.1
MOV P1 #06
SET P3.2
CLR P3.2
[/center]
After executing this program the output in segment 1 is "1" and
"2" in segment 2.
I hope it helps you. :D :D
Just ask again if there is a part that isn't clear to you.

Ma'am pano po i-convert yung frequency into hex (yung mismong
ilalagay na sa program) ?
nabasa ko lang pang sana makatulong :)
The clock rate typically refers to the frequency at which a chip
like a central processing unit (CPU), one core of a multi-core
processor, is running and is used as an indicator of the
processor's speed. It is measured in clock cycles per second or
its equivalent, the SI unit hertz (Hz). The clock rate of the
first generation of computers was measured in hertz or kilohertz
(kHz), but in the 21st century the speed of modern CPUs is
commonly advertised in GigaHertz (GHz). This metric is most
useful when comparing processors within the same family, holding
constant other features that may impact performance. Video card
and CPU manufacturers commonly select their highest performing
units from a manufacturing batch and set their maximum clock
rate higher, fetching a higher price.

Actually, hindi talaga sya pede pagsabayin pero pede mo syang
i-alternate. Una mong palabasin yung output para sa sounds sunod
yung output ng ilaw. Bale lagi silang magkasunod imbes na
nagdedelay tayo yung ilaw na output na po yung delay natin.
