PSOC3 digital filter does not deal correctly with overshot ?

Hello

I have the following problem : with a signed square numeric input on HOLDAH register and an offset on the output, looks like the filter does not deal correctly with overshots. (scope picture attached).


Please note that the offset out of DMA was done with a register and a not gate (picture attached)

I attach my project too.
if I am right, the filter is not reliable,

could anybody help ?
