TIMERS
The M37210M3-XXXSP has 4 timers: timer 1, timer 2, timer 3 and
timer 4. All timers are 8-bit timers with the 8-bit timer latch. The timer
block diagram is shown in Figure 7.
All of the timers count down and their divide ratio is 1/(n+1), where n
is the value of timer latch. The value is set to a timer at the same time
by writing a count value to the corresponding timer latch (addresses
00F0
16
to 00F3
16
: timers 1 to 4).
The count value is decremented by 1. The timer interrupt request bit
is set to “1” by an timer overflow at the next count pulse after the
16.
”
(1) Timer 1
Timer 1 can select one of the following count sources:
f(X
IN
)/16
f(X
IN
)/4096
The count source of timer 1 is selected by setting bit 0 of the timer 12
mode register (address 00F4
16
).
Timer 1 interrupt request occurs at timer 1 overflow.
(2) Timer 2
Timer 2 can select one of the following count sources:
f(X
IN
)/16
Timer 1 overflow signal
External clock from the P3
2
/TIM2 pin
The count source of timer 2 is selected by setting bits 4 and 1 of the
timer 12 mode register (address 00F4
16
). When timer 1 overflow
signal is a count source for the timer 2, the timer 1 functions as an 8-
bit prescaler.
Timer 2 interrupt request occurs at timer 2 overflow.
(3) Timer 3
Timer 3 can select one of the following count sources:
f(X
IN
)/16
External clock from the P3
3
/TIM3 pin and the H
SYNC
pin
The count source of timer 3 is selected by setting bits 5 and 0 of the
timer 34 mode register (address 00F5
16
).
Timer 3 interrupt request occurs at timer 3 overflow.
(4) Timer 4
Timer 4 can select one of the following count sources:
f(X
IN
)/16
f(X
IN
)/2
Timer 3 overflow signal
The count source of timer 3 is selected by setting bits 4 and 1 of the
timer 34 mode register 2 (address 00F5
16
). When timer 3 overflow
signal is a count source for the timer 4, the timer 3 functions as an 8-
bit prescaler.
Timer 4 interrupt request occurs at timer 4 overflow.
At reset, timers 3 and 4 are connected by hardware and “FF
16
” is
automatically set in timer 3; “07
16
” in timer 4. The f(X
IN
)/16 is se-
lected as the timer 3 count source. The internal reset is released by
timer 4 overflow at these state, the internal clock is connected .
At execution of the STP instruction, timers 3 and 4 are connected by
hardware and “FF
16
” is automatically set in timer 3; “07
16
” in timer 4.
However, the f(X
IN
)16 is not selected as the timer 3 count source. So
set bit 0 of the timer 34 mode register (address 00F5
16
) to “0” before
the execution of the STP instruction (f(X
IN
)16 is selected as the timer
3 count source). The internal STP state is released by timer 4 over-
flow at these state, the internal clock is connected .
Because of this, the program starts with stable clock.
The structure of timer-related registers is shown in Figure 6.
