Comparator
When a comparison of the up counter value and timer
register values shows a match, the up counter is
cleared to “0” and an interrupt (INTT0-INTT3) is generated. If
timer flip-flop inversion is enabled, the timer flip-flop value
is inverted at the same time.
Timer Flip-flop
This flip-flop is inverted by the interval timer match
detect signals (comparator output) and the value can
be output to the timer output pins TO1 (also used a
P66) and TO3 (also used as P67).
One each of these timer flip-flops is provided for the
timer 0/1 pair and the timer 2/3 pair. These timer flip-
flops are called TFF1 and TFF3. TFF1 outputs to TO1
and TFF3 outputs to TO3.
The following explains the operation of the 8-bit timers.
(1)
8-Bit Timer Mode
The four 8-bit interval timers 0, 1, 2 and 3 can be used
independently. The operation is the same for all and
timer 1 will be used for explanatory purposes.
When interrupts are generated in a fixed cycle
To use timer 1 for generating interrupts (INTT1) in a
fixed cycle, first stop timer 1 and then load the operation
mode, input clock and cycle to the T01MOD TREG1 reg-
isters. Next, enable interrupt INTT1 and then start timer
1 counting.
Example:
Use the following procedure to load the
registers to generate timer 1 interrupts
every 40 microseconds at fc = 16MHz.
