Remarks
TI000
P33/TO00/TIP00/TOP00
Shares the pin with TO00.
TI001
P34/TO00/TIP01/TOP01
Shares the pin with TO00.
P33/TI000/TIP00/TOP00
TM00
TO00
P34/TI001/TIP01/TOP01
Assigned to two pins, P33 and P34.
TI010
P35/TO01
Shares the pin with TO01.
TI011
P50/KR0/RTP00
P32/ASCK0/ADTRG
TM01
TO01
P35/TI010
Assigned to two pins, P32 and P35.
(a) For TM00 channel
When using the output of TO00 that functions alternately as P33, only a software trigger
(TOC00.OSPT00 bit) can be used as the trigger in the one-shot pulse output mode. A P33/TI000 pin
input signal cannot be used as the trigger since TI000 and TO00 share a pin and are used alternately.
A TI000 pin input signal can be used as the trigger, however, when using the output of TO00 that
functions alternately as P34.
When using the output of TO00 that functions alternately as P33, the timer output inversion operation
using the valid edge of the TI000 pin input cannot be performed. The valid edge cannot be input to the
P33/TI000 pin since TI000 and TO00 share a pin and are used alternately. Set the TMC00.TMC001 bit
to 0 in this event.
The timer output inversion operation using the valid edge of the TI000 pin input can be performed,
however, when using the output of TO00 that functions alternately as P34.
(b) For TM01 channel
When using the output of TO01 that functions alternately as P35, only a software trigger
(TOC01.OSPT01 bit) can be used as the trigger in the one-shot pulse output mode. A P35/TI010 pin
input signal cannot be used as the trigger since TI010 and TO01 share a pin and are used alternately.
A TI010 pin input signal can be used as the trigger, however, when using the output of TO01 that
functions alternately as P32.
When using the output of TO01 that functions alternately as P35, the timer output inversion operation
using the valid edge of the TI010 pin input cannot be performed. The valid edge cannot be input to the
P35/TI010 pin since TI010 and TO01 share a pin and are used alternately. Set the TMC01.TMC011 bit
to 0 in this event.
The timer output inversion operation using the valid edge of the TI010 pin input can be performed,
however, when using the output of TO01 that functions alternately as P32.
