PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
G
Timer X
Timer X can be selected in one of 4 operating modes by setting the
timer X mode register.
Timer Mode
The timer counts the signal selected by the timer X count source
selection bits.
Pulse Output Mode
The timer counts the signal selected by the timer X count source
selection bits, and outputs a signal whose polarity is inverted each
time the timer value reaches “0”, from the CNTR
0
pin.
When the CNTR
0
active edge switch bit is “0”, the output of the
CNTR
0
pin is started with an “H” output. At “1”, this output is started
with an “L” output. When using a timer in this mode, set the port
P1
4
direction register to output mode. Also, in the pulse output
mode, the inverted waveform of pulse output from CNTR
0
pin can
be output from TX
OUT
pin by setting the P0
3
/TX
OUT
output valid
bit to “1” . When using a timer in this mode, set the port P0
3
direc-
tion register to output mode.
Event Counter Mode
The operation in the event counter mode is the same as that in
the timer mode except that the timer counts the input signal from
the CNTR
0
pin.
When the CNTR
0
active edge switch bit is “0”, the timer counts
the rising edge of the CNTR
0
pin. When this bit is “1”, the timer
counts the falling edge of the CNTR
0
pin.
Pulse Width Measurement Mode
When the CNTR
0
active edge switch bit is “0”, the timer counts
the signal selected by the timer X count source selection bit while
the CNTR
0
pin is “H”. When this bit is “1”, the timer counts the
signal while the CNTR
0
pin is “L”.
In any mode, the timer count can be stopped by setting the timer
X count stop bit to “1”. Each time the timer overflows, the interrupt
request bit is set.

Note :
System operates using a ring oscillator as a count source by setting
the ring oscillator to oscillation enabled by bit 3 of CPUM.
