CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER

8.98/16-bit Capture Timer/Counter Operation in Each Mode

This section describes the operation of the 8/16-bit capture timer/counter when it switches to the sleep or stop mode or when a halfway stop request is issued during the operation of the interval timer or counter function.

■Operation in Standby Mode and at Halfway Stop

Figure 8.9-1shows the counter value states if the 8/16-bit capture timer/counter switches to the sleep or stop mode or when a halfway stop request is issued when the interval timer or counter function is in operation (at timer 0 operation).

When the counter switches to the stop mode, it retains the value and stops. If the stop mode is released by an external interrupt, the counter starts its operation at the retained value, and so the first interval time and external clock count are incorrect. When the stop mode is released, the 8/16-bit capture timer/counter must be initialized.

When the counter is temporarily stopped (TSTR0 = 0), it retains its value and stops. If the subsequent operation is continued (TSTR0 = 1), the count value is cleared and the counter is restarted.

*:	When the pin state specification bit (SPL) of the standby control register (STBC) is "1" and the TO pin is not
	pulled up, the TO pin in the stop mode becomes Hi-Z. When the pin state specification bit (SPL) is "0", the value
	immediately before the 8/16-bit capture timer/counter switches to the stop mode is retained.
