sample period must be calculated based on the resultant, longer, MCU_CLK frequency. In
this case, an external clock signal on pins C0, C1, or T2 should have a duration longer than
one MCU machine cycle, t

SFR, TCON
Timer 0 and Timer 1 share the SFR, TCON, that controls these timers and provides
information about them. See
Bits IE0 and IE1 are not related to Timer/Counter functions, but they are set by hardware
when a signal is active on one of the two external interrupt pins, EXTINT0 and EXTINT1. For
system information on all of these interrupts, see
Bits IT0 and IT1 are not related to Timer/Counter functions, but they control whether or not
the two external interrupt input pins, EXTINT0 and EXTINT1 are edge or level triggered.

Timer 1 overflow interrupt flag. Set by hardware upon overflow.
Automatically cleared by hardware after firmware services the
interrupt for Timer 1.
Timer 1 run control. 1 = Timer/Counter 1 is on, 0 =
Timer/Counter 1 is off.
Timer 0 overflow interrupt flag. Set by hardware upon overflow.
Automatically cleared by hardware after firmware services the
interrupt for Timer 0.
Timer 0 run control. 1 = Timer/Counter 0 is on, 0 =
Timer/Counter 0 is off.
Interrupt flag for external interrupt pin, EXTINT1. Set by
hardware when edge is detected on pin. Automatically cleared
