7.6 Cautions for 16-Bit Timer/Event Counters 00 and 01
(1) Restrictions for each channel of 16-bit timer/event counter 0n
(2) Timer start errors
(3) Setting of CR00n and CR01n (clear & start mode entered upon a match between TM0n and CR00n)

As interval timer
As square-wave output
As external event counter
As clear & start mode entered by
TI00n pin valid edge input
As free-running timer
As PPG output
As one-shot pulse output
As pulse width measurement
Table 7-3 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 TM0n is started asynchronously to the count pulse.
Set a value other than 0000H to CR00n and CR01n (TM0n cannot count one pulse when it is used as an external
event counter).
Remark n = 0:
Operation
n = 0, 1: 78K0/KE2 products whose flash memory is at least 48 KB, and 78K0/KF2 products

Using timer output (TO0n) is prohibited when detection of the valid edge of the TI01n pin is
used. (TOC0n = 00H)
Setting the same value to CR00n and CP01n is prohibited.
Using timer output (TO0n) is prohibited (TOC0n = 00H)
0000H ≤ CP01n < CR00n ≤ FFFFH
