6.6 Cautions for 16-Bit Timer/Event Counter 00
(1) Restrictions for each channel of 16-bit timer/event counter 00
(2) Timer start errors
(3) Setting of CR000 and CR010 (clear & start mode entered upon a match between TM00 and CR000)

As interval timer
As square-wave output
As external event counter
As clear & start mode entered by
TI000 pin valid edge input
As free-running timer
As PPG output
As one-shot pulse output
As pulse width measurement
Table 6-3 shows the restrictions for each channel.
An error of up to one clock may occur in the time required for a match signal to be generated after timer start. This is
because counting TM00 is started asynchronously to the count pulse.
Set a value other than 0000H to CR000 and CR010 (TM00 cannot count one pulse when it is used as an external
event counter).
Operation
Table 6-3. Restrictions for Each Channel of 16-Bit Timer/Event Counter 00
TM00 count value
Count pulse
Using timer output (TO00) is prohibited when detection of the valid edge of the TI010 pin is
used. (TOC00 = 00H)
Setting the same value to CR000 and CP010 is prohibited.
Using timer output (TO00) is prohibited (TOC00 = 00H)
0000H ≤ CP010 < CR000 ≤ FFFFH
