CHAPTER 6 16-BIT TIMER/EVENT COUNTER 00

CR000
(i) When CR000 is used as a compare register
The value set in CR000 is constantly compared with the TM00 count value, and an interrupt request signal
(INTTM000) is generated if they match. The value is held until CR000 is rewritten.
Caution CR000 does not perform the capture operation when it is set in the comparison mode, even
if a capture trigger is input to it.
(ii) When CR000 is used as a capture register
The count value of TM00 is captured to CR000 when a capture trigger is input.
As the capture trigger, an edge of a phase reverse to that of the TI000 pin or the valid edge of the TI010 pin
can be selected by using CRC00 or PRM00.

CR010
(i) When CR010 is used as a compare register
The value set in CR010 is constantly compared with the TM00 count value, and an interrupt request signal
(INTTM010) is generated if they match.
Caution CR010 does not perform the capture operation when it is set in the comparison mode, even
if a capture trigger is input to it.
(ii) When CR010 is used as a capture register
The count value of TM00 is captured to CR010 when a capture trigger is input.
It is possible to select the valid edge of the TI000 pin as the capture trigger. The TI000 pin valid edge is set
by PRM00.
