Functions

At reset R W

• This register stores a value which is obtained

by counting a following interval with the

counter sampling clock.

Rising interval

Falling interval

Both edges interval (Note)

(Selected by interrupt edge selection register)

• Read exclusive register

Note: When the noise filter sampling clock selection bits (bits 2, 3) of

the interrupt interval determination control register is “00”, the

both-sided edge detection function cannot be used.
