6.4.4 External event counter operation
counter 0n (TM0n).
cleared to 0 and the interrupt request signal (INTTM00n) is generated.
prescaler mode register 0n (PRM0n).
TI00n pin is detected twice, thus eliminating noise with a short pulse width.

The basic operation setting procedure is as follows.
<1> Set the CRC0n register (see Figure 6-31 for the set value).
<2> Set the count clock by using the PRM0n register.
<3> Set any value to the CR00n register (0000H cannot be set).
<4> Set the TMC0n register to start the operation (see Figure 6-31 for the set value).
Remarks 1. For the setting of the TI00n pin, see 6.3 (5) Port mode register 0 (PM0).
The external event counter counts the number of external clock pulses input to the TI00n pin using 16-bit timer
TM0n is incremented each time the valid edge specified by prescaler mode register 0n (PRM0n) is input.
When the TM0n count value matches the 16-bit timer capture/compare register 00n (CR00n) value, TM0n is
Input a value other than 0000H to CR00n (a count operation with 1-bit pulse cannot be carried out).
Any of three edges rising, falling, or both edges can be selected using bits 4 and 5 (ES0n0 and ES0n1) of
Sampling is performed using the internal clock (f
