CHAPTER 6 16-BIT TIMER/EVENT COUNTER 00
User’s Manual U16994EJ6V0UD
104
The external event counter counts the number of external clock pulses to be input to the TI000 pin with using 16-bit
timer counter 00 (TM00).
TM00 is incremented each time the valid edge specified by prescaler mode register 00 (PRM00) is input.
When the TM00 count value matches the 16-bit timer capture/compare register 000 (CR000) value, TM00 is
cleared to 0 and the interrupt request signal (INTTM000) is generated.
Input a value other than 0000H to CR000. (A count operation with a pulse cannot be carried out.)
The rising edge, the falling edge, or both edges can be selected using bits 4 and 5 (ES000 and ES010) of
prescaler mode register 00 (PRM00).
Because an operation is carried out only when the valid edge of the TI000 pin is detected twice after sampling with
the internal clock (fXP), noise with a short pulse width can be removed.
