s NOTES ON USE

When the prescaler is used in external clock mode, and the prescaler output signal is used as the timer operating

clock, use the following settings.

Set the timer operating clock to ’External clock’ (TCR bits 10, 9 = “01”), and connect the prescaler output

pin PRSCK externally to the timer external clock input pin CLK.

When the prescaler and timer are set to the following modes, the timer output signal OUT will not change at the

anticipated time:

Prescaler: External clock mode (PRESCALER REGISTER bit15 = “1”).

Timer: Prescaler internal output signal used as operating clock, without using the external input pin (TCR bit 10,

9 = “10”).
