Panasonic MN103001G/F01K - Manual (Page 279)

16-bit Timers
11-25
■ Procedure for ending operation
(1) Disable timer startup by an external trigger.
Set TM10TGE in the TM10MD register to "0".
(2) Stop the counting operation.
Set TM10CNE in the TM10MD register to "0".
If TM10TGE and TM10CNE are both set to "0" simultaneously, there is a possibility that TM10CNE will be set
again, depending on the pin input timing. Therefore, always be sure to set TM10TGE to "0" first, and then set
TM10CNE to "0".
