is there any function could disable timer?
for example Timer 2 runs with counts=100, now i disable the timer 2 ,i want to timer 2 pause,then i handle some code. after that code,i enable the timer 2, i want timer 2 could keep running start from counts 100.
‘’’
disable the timer 2(timer 2 maybe counts =100,now it pause)
myfun()
enable the timer 2(keep running)

Timers have a deinit() and init() method. When you reinit you can pass new settings:

extmod/machine_timer.c

          typedef soft_timer_entry_t machine_timer_obj_t;
          
          const mp_obj_type_t machine_timer_type;
          
          static void machine_timer_print(const mp_print_t *print, mp_obj_t self_in, mp_print_kind_t kind) {
              machine_timer_obj_t *self = MP_OBJ_TO_PTR(self_in);
              qstr mode = self->mode == SOFT_TIMER_MODE_ONE_SHOT ? MP_QSTR_ONE_SHOT : MP_QSTR_PERIODIC;
              mp_printf(print, "Timer(mode=%q, period=%u)", mode, self->delta_ms);
          }
          
          static mp_obj_t machine_timer_init_helper(machine_timer_obj_t *self, size_t n_args, const mp_obj_t *pos_args, mp_map_t *kw_args) {
              enum { ARG_mode, ARG_callback, ARG_period, ARG_tick_hz, ARG_freq, };
              static const mp_arg_t allowed_args[] = {
                  { MP_QSTR_mode,         MP_ARG_KW_ONLY | MP_ARG_INT, {.u_int = SOFT_TIMER_MODE_PERIODIC} },
                  { MP_QSTR_callback,     MP_ARG_KW_ONLY | MP_ARG_OBJ, {.u_obj = MP_OBJ_NULL} },
                  { MP_QSTR_period,       MP_ARG_KW_ONLY | MP_ARG_INT, {.u_int = 0xffffffff} },
                  { MP_QSTR_tick_hz,      MP_ARG_KW_ONLY | MP_ARG_INT, {.u_int = 1000} },
                  { MP_QSTR_freq,         MP_ARG_KW_ONLY | MP_ARG_OBJ, {.u_rom_obj = MP_ROM_NONE} },
              };
          
              // Parse args
