SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
(2) Event counter mode [01]
Figure 15 shows the bit configuration of the timer Ai mode register
during event counter mode. In event counter mode, the bit 0 of the
timer Ai mode register must be “1” and bit 1 and 5 must be “0”.
The input signal from the TAiIN pin is counted when the count start
flag shown in Figure 13 is “1“ and counting is stopped when it
is “0”.
Count is performed at the fall of the input signal when bit 3 is “0”
and at the rise of the signal when it is “1”.
In event counter mode, whether to increment or decrement the
count can be selected with the up-down flag or the input signal
from the TAiOUT pin.
When bit 4 of the timer Ai mode register is “0”, the up-down flag is
used to determine whether to increment or decrement the count
(decrement when the flag is “0” and increment when it is “1”). Fig-
ure 16 shows the bit configuration of the up-down flag.
When bit 4 of the timer Ai mode register is “1”, the input signal
from the TAiOUT pin is used to determine whether to increment or
decrement the count. However, note that bit 2 must be “0” if bit 4
is “1” because if bit 2 is “1”, TAiOUT pin becomes an output pin with
pulse output.
The count is decremented when the input signal from the TAiOUT
pin is “L” and incremented when it is “H”. Determine the level of
the input signal from the TAiOUT pin before valid edge is input to
the TAiIN pin.
An interrupt request signal is generated and the interrupt request
bit in the timer Ai interrupt control register is set when the counter
reaches 000016 (decrement count) or FFFF16 (increment count).
At the same time, the contents of the reload register is transferred
to the counter and the count is continued.
When bit 2 is “1” and the counter reaches 000016 (decrement
count) or FFFF16 (increment count), the waveform reversing polar-
ity is output from TAiOUT pin.
If bit 2 is “0”, TAiOUT pin can be used as a normal port pin. How-
ever, if bit 4 is “1“ and the TAiOUT pin is used as an output pin, the
output from the pin changes the count direction. Therefore, bit 4
should be “0” unless the output from the TAiOUT pin is to be used
to select the count direction.
