Structure of timer Y mode register (
φ is internal system clock)
Operating Modes
(1) Timer mode
This mode is available with timer X and timer Y.
Count source
The count source for timer X and Y is the output of the corre-
sponding clock divider. The division ratio can be selected by the
timer Y mode register.
Operation
Both timers X and Y are down counters. On a timer underflow,
the corresponding timer interrupt request bit will be set to “1”, the
contents of the corresponding timer latches will be reloaded to
the counters and counting continues.
(2) Bi-phase counter mode (quadruplicate)
This mode is available with timer X only.
Count source
The count sources are P14/CNTR0 and the P13/TX0 pins.
Operation
Timer X will count both rising and falling edges on both input pins
(see above). Refer to Timer X bi-phase counter mode operation
for the timing chart of the bi-phase counter mode.
The count direction is determined by the edge polarity and level
of count source inputs and may change during the count opera-
tion. Refer to the table below.
On a timer over- or underflow, the corresponding interrupt
request bit will be set to “1” and counting continues.
