Timer / Counter 0 and 1
Timer/Counter 0 and 1 can be used in four operating modes as listed in
Table 6
:
In the “timer” function (C/T = ‘0’) the register is incremented every machine cycle. Therefore the
count rate is
f
OSC
/6.
In the “counter” function the register is incremented in response to a 1-to-0 transition at its
corresponding external input pin (P3.4/T0, P3.5/T1). Since it takes two machine cycles to detect a
falling edge the max. count rate is
f
OSC
/12. External inputs INT0 and INT1 (P3.2, P3.3) can be
programmed to function as a gate to facilitate pulse width measurements.
Figure 11
illustrates the
input clock logic.
