TIMER
There are eight 16-bit timers. They are divided by type into timer A
(5) and timer B (3).
The timer I/O pins are shared with I/O pins for port P5 and P6. To
use these pins as timer input pins, the data direction register bit
corresponding to the pin must be cleared to “0” to specify input
mode.
TIMER A
Figure 11 shows a block diagram of timer A.
Timer A has four modes; timer mode, event counter mode, one-
shot pulse mode, and pulse width modulation mode. The mode is
selected with bits 0 and 1 of the timer Ai mode register (i = 0 to 4).
Each of these modes is described below.
(1) Timer mode [00]
Figure 12 shows the bit configuration of the timer Ai mode register
during timer mode. Bits 0, 1, and 5 of the timer Ai mode register
must always be “0” in timer mode.
Bit 3 is ignored if bit 4 is “0”.
Bits 6 and 7 are used to select the timer counter source.
The counting of the selected clock starts when the count start flag
is “1” and stops when it is “0”.
Figure 13 shows the bit configuration of the count start flag. The
counter is decremented, an interrupt is caused and the interrupt
request bit in the timer Ai interrupt control register is set when the
contents becomes 000016. At the same time, the contents of the
reload register is transferred to the counter and count is contin-
ued.
