Structure of Timer X mode register
Timer Y
Timer Y is a 16 bit timer with a 16-bit reload latch supporting the fol-
lowing operating modes:
(1) Timer mode
(3) Event counter mode
(5) Pulse period measurement mode
(6) H/L pulse width measurement mode
These modes can be selected by the timer Y mode register (TYM).
In the timer, pulse period- and pulse width measurement modes’
the timer’s count source can be selected by the timer Y count
source selection bits. Please refer to Fig. 19.
On read or write access to timer Y, note that the high-order and low-
order bytes must be accessed in a specific order.
Write method
When writing to timer Y, write the low-order byte first. The data writ-
ten is stored in a temporary register which is assigned to the same
address as TYL. Next, write the high-order byte. When this is fin-
ished, the data is placed in the timer Y high-order reload latch and
the low-order byte is transferred from its temporary register to the
timer Y low-order reload latch.
Read method
When reading the timer Y, read the high-order byte first. This
causes the timer Y high- and low-order bytes to be transferred to
temporary registers being assigned to the same addresses as TYH
and TYL. Next, read the low-order byte which is read from the tem-
porary register. This method assures the correct timer value can be
read during timer count operation.
Timer Y count stop control
Regardless of the actual operating mode, timer Y can be stopped
by setting the timer Y count stop bit (bit 7 of the timer Y mode regis-
ter) to “1”.
Timer X data write control bit
0 : Data is written to latch and timer
1 : Data is written to latch only
Not used (“0” when read, do not write “1”)
Timer X mode bits
b5 b4
0 0: Timer mode
0 1: Bi-phase counter mode
1 0: Event counter mode
1 1: Pulse width measurement mode
CNTR0 polarity selection bit
0 : For event counter mode, rising edge active
For interrupt request, falling edge active
For pulse width measurement mode, measure “H” period
1 : For event counter mode, falling edge active
For interrupt request, rising edge active
For pulse width measurement mode, measure “L” period
Timer X stop control bit
0 : Timer counting
1 : Timer stopped
