Comparator
A comparator compares the value in the up-counter
with the values to which the timer register is set. When
they match, the up-counter is cleared to zero and an
interrupt signal (INTT0 ~ INTT3) is generated. If the
timer flip-flop inversion is enabled, the timer flip-flop is
inverted at the same time.
Timer flip-flop (timer F/F)
The status of the timer flip-flop is inverted by the match
detect signal (comparator output) of each interval timer
and the value can be output to the timer output pins TO1
(also used as P55) and TO3 (also used as P57).
A timer F/F is provided for each pair of timer 0 and timer 1
as well as that of timer 2 and timer 3 and is called TFF1
and TFF3. TFF1 is output to TO1 pin, while TFF3 is output
to TO3 pin.
The operation of 8-bit timers will be described below:
(1)
8-bit timer mode
Four interval timers 0, 1, 2, and 3 can be used inde-
pendently as an 8-bit interval timers. All interval timers
operate in the same manner, thus only the operation of
timer 1 will be explained below.
Generating interrupts in a fixed cycle
To generate timer 1 interrupt at constant intervals
using using timer 1 (INTT1), first stop timer 1 then set
the operation mode, input clock, and synchronization
to T01MOD and TREG1, respectively. Then, enable
interrupt INTT1 and start the counting of timer 1.
Example: To generate timer 1 interrupt every 40
microseconds at fc = 16MHz, set each reg-
ister in the following manner.
Use the following table for selecting the input clock:
