Gating control when set. Timer/Counter “n” is enabled only while “INTn” pin is high and
TMOD.7
“TRn” control pin is set. when cleared Timer “n” is enabled whenever “TRn” control bit is set.

8-bit auto-reload Timer/Counter: “THn” holds a value which is to be reloaded
into “TLn” each time it overflows.
1
(Timer 0) TL0 is an 8-bit Timer/Counter controlled by the standard Timer 0 control bits.
TH0 is an 8-bit timer only controlled by Timer 1 control bits.
1
(Timer 1) Timer/Counter 1 stopped.
