TMH2 output signal
<3> When the TM52 and CR52 (= FFH) values match, TM52 is cleared to 00, and the match signal causes TM000
TI52 & TOH2
to start counting up. Then, when the TM000 and CR000 values match, TM00 is cleared to 0000H, and a
match interrupt signal (INTTM000) is generated.
If input enable for the TI52 pin is controlled, external event count values within the input enable periods for the
TI52 pin can be measured, by reading TM52, the TM00 count value, and TMIF52 via interrupt servicing by the
TMH2 interrupt request signal (INTTMH2).
