Timer
SFRs
As
mentioned
before,
the 8051
has two
timers
which
each
function
essentially
the same
way. One
timer is
TIMER0
and the
other is
TIMER1.
The two
timers
share
two SFRs
(TMOD
and TCON)
which
control
the
timers,
and each
timer
also has
two SFRs
dedicated
solely
to
itself
(TH0/TL0
and
TH1/TL1).
