SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
When bit 2 of the timer Ai mode register is “1”, the output is gener-
ated from TAiOUT pin. The output is toggled each time the contents
of the counter reaches to 000016. When the contents of the count
start flag is “0”, “L” is output from TAiOUT pin.
When bit 2 is “0”, TAiOUT can be used as a normal port pin. When
bit 4 is “0”, TAiIN can be used as a normal port pin. When bit 4 is
“1”, counting is performed only while the input signal from the
TAiIN pin is “H” or “L” as shown in Figure 14. Therefore, this can
be used to measure the pulse width of the TAiIN input signal.
Whether to count while the input signal is “H” or while it is “L” is
determined by bit 3. If bit 3 is “1”, counting is performed while the
TAiIN pin input signal is “H” and if bit 3 is “0”, counting is performed
while it is “L”.
Note that the duration of “H” or “L” on the TAiIN pin must be two or
more cycles of the timer count source.
When data is written to timer Ai register with timer Ai halted, the
same data is also written to the reload register and the counter.
When data is written to timer Ai which is busy, the data is written to
the reload register, but not to the counter. The counter is reloaded
with new data from the reload register at the next reload timer. The
contents of the counter can be read at any time.
When the value set in the timer Ai register is n, the timer frequency
dividing ratio is 1/(n + 1).
