Note When setting the timer 2 count clock/control edge selection register 0 (CSE0)’s CESE1 bit to 1 and CESE0 bit
to 0.
Remarks 1. T: Digital filter sampling clock
T can be selected by setting the following registers.
• When using TIUDn, TCUDn, and TCLRn (n = 10, 11), the following cycles can be selected by
setting the NRCn1 and NRCn0 bits of timer n noise elimination time selection register (NRCn).
When fXX/2 is selected for the timer n base clock: fXX/2, fXX/4, fXX/8, fXX/16
When fXX/4 is selected for the timer n base clock: fXX/4, fXX/8, fXX/16, fXX/32
• When using TCLR2 and TI2, the following cycles can be selected by setting the PRM2 bit of the
timer 1/timer 2 clock selection register (PRM02).
When fXX/2 is selected for the timer 2 base clock: fXX/2
When fXX/4 is selected for the timer 2 base clock: fXX/4
• When using TCLR3 and TI3, the following cycles can be selected by setting the NRC31 and
NRC30 bits of timer 3 noise elimination time selection register (NRC3).
When fXX is selected for the timer 3 base clock: fXX/2, fXX/4, fXX/8, fXX/16
When fXX/2 is selected for the timer 3 base clock: fXX/4, fXX/8, fXX/16, fXX/32
