The TM0 count operation is controlled by the CE0 bit of the timer control register 0 (TMC0) in the same way as with basic
When the CE0 bit is set (1) by software, the contents of TM0 are set to 0000H and the up-count is started on the initial count
When the CE0 bit is cleared (0) by software during a TM0 count operation, the contents of TM0 are set to 0000H immediately
