5.6.5 Counter operating modes5.6.5.1 Count continuouslyn In this operating mode the counter counts starting with the load value.n When the counter counts forward and reaches the upper count limit and anothercounting pulse in positive direction arrives, it jumps to the lower count limit and countsfrom there on.n When the counter counts backwards and reaches the lower count limit and anothercounting pulse in negative direction arrives, it jumps to the upper count limit andcounts from there on.n The counter limits are fix set to maximum range.n With overflow or underflow the status bits STS_OFLW respectively STS_UFLW areset in SFB 47. These bits remain set until these are reset with RES_STS. If enabledadditionally a hardware interrupt is triggered.Limits Valid range of valuesLower count limit -2 147 483 648 (-231)Upper count limit +2 147 483 647 (231 -1)VIPA System SLIO Deployment I/O peripheryCounting > Counter operating modesHB300 | CPU | 013-CCF0R00 | en | 19-30 135
