[Notes on use]
Notes 1 : When there is no necessity for changing the timer X underflow time
in , omit it.
2 : When writing to the latch only is selected as the timer X write control,
the timer X value (TXL, TXH) is rewritten at the first underflow
after .
3 : Execute another timer X interrupt processing in Œ to .
