(2) Setting LVS00 and LVR00
Set LVS00 and LVR00 using the following procedure.
Caution Be sure to set LVS00 and LVR00 following steps <1>, <2>, and <3> above.
<1> The TO00 pin output goes high when LVS00 and LVR00 = 10.
<2> The TO00 pin output goes low when LVS00 and LVR00 = 01 (the pin output remains unchanged from the
<3> The timer starts operating when TMC003 and TMC002 are set to 01, 10, or 11. Because LVS00 and
<4> The output level of the TO00 pin is inverted each time an interrupt signal (INTTM000) is generated.
high level even if LVS00 and LVR00 are cleared to 00).
LVR00 were set to 10 before the operation was started, the TO00 pin output starts from the high level.
After the timer starts operating, setting LVS00 and LVR00 is prohibited until TMC003 and TMC002 = 00
(disabling the timer operation).
Step <2> can be performed after <1> and before <3>.
