To generate a cyclical timer interrupt, use Tmr.CycInt to setup
the interrupt frequency. The time between the interrupts is
specified in servo cycles, (at FS) where each servo cycle is
currently 1 ms.
When Tmr.CycInt is set, the internal interrupt-timer is also set
to the same value.
Therefore, the first interrupt occurs after Tmr.CycInt servo
cycles.
To generate a single-shot interrupt, setup Tmr.CycInt and
enable the interrupt;
Do not re-enable the interrupt when exiting the interrupt
routine.
Tmr.T0 2 -2 31 ..2 31 -1 RW
This is the time-value for timer 0. The timers are implemented by
using an adjustment offset from an absolute time. By writing to
Tmr.T0 the offset, Tmr.A0 changes so Tmr.T0 shows the
desired time.
To increment or decrement this time, by a fixed amount without
risking that the timer will change values during the operation, add
or subtract from Tmr.A0 instead of Tmr.T0.
Tmr.A0 3 -2 31 ..2 31 -1 RW
This is the offset adjustment value for timer 0.
Tmr.T1 4 -2 31 ..2 31 -1 RW
This is the time-values for timer 1. The timers are implemented
by using an adjustment offset from an absolute time. By writing to
Tmr.T1 the offset, Tmr.A1 is changed so Tmr.T1 shows the
desired time.
To increment or decrement this time, by a fixed amount without
risking timer value changes during the operation, add or subtract
from Tmr.A1 instead of Tmr.T1.
Tmr.A1 5 -2 31 ..2 31 -1 RW
This is the offset adjustment value for timer 1.
Tmr.T2 6 -2 31 ..2 31 -1 RW
This is the time-values for timer 2. The timers are implemented
by using an adjustment offset from an absolute time. By writing to
Tmr.T2 the offset, Tmr.A2 is changed so Tmr.T2 shows the
desired time.
