Count operation
Up count
Counter value “000016” is transferred to reload register at measurement
pulse's effective edge and the timer continues counting
Count start condition
Count start flag is set (= 1)
Count stop condition
Count start flag is reset (= 0)
Interrupt request generation timing When measurement pulse's effective edge is input (Note 1)
When an overflow occurs. (Simultaneously, the timer Bi overflow flag
changes to “1”. The timer Bi overflow flag changes to “0” when the count
start flag is “1” and a value is written to the timer Bi mode register.)
TBiIN pin function
Measurement pulse input
Read from timer
When timer Bi register is read, it indicates the reload register’s content
(measurement result) (Note 2)
Write to timer
Cannot be written to
(3) Pulse period/pulse width measurement mode
In this mode, the timer measures the pulse period or pulse width of an external signal. (See Table 1.13.8.)
However, this function cannot be used since timer B1 does not have input port. Figure 1.13.19 shows the
timer Bi mode register in pulse period/pulse width measurement mode. Figure 1.13.20 shows the opera-
tion timing when measuring a pulse period. Figure 1.13.21 shows the operation timing when measuring
a pulse width.

Note 1: An interrupt request is not generated when the first effective edge is input after the timer has started counting.
Note 2: The value read out from the timer Bi register is indeterminate until the second effective edge is input after the timer.

Note 1: The timer Bi overflow flag changes to “0” when the count start flag is “1” and a value is written to the
timer Bi mode register. This flag cannot be set to “1” by software.
Note 2: Timer B0, timer B3.
Note 3: Timer B1, timer B2, timer B4, timer B5.
0 (Fixed to “0” in pulse period/pulse width measurement mode; i = 0, 3)
(Note 2)
(Note 3)
Nothing is assigned (i = 1, 2, 4, 5).
In an attempt to write to this bit, write “0”. The value, if read, turns out to be
indeterminate.
