Timer/ Counter 0 and 1
Timer/Counter 0 and 1 can be used in four operating modes as listed in
table 7
:
Table 7
Timer/Counter 0 and 1 operating modes
In “timer” function (C/T = ‘0’) the register is incremented every machine cycle. Therefore the count
rate is
f
OSC
/12.
In “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
/24. External inputs INT0 and INT1 (P3.2, P3.3) can be
programmed to function as a gate to facilitate pulse width measurements.
Figure 7
illustrates the
input clock logic.
