01 PS_TH & PS_TL (PS high & low threshold) are active as hysteresis:

PS_TH and PS_TL are working as a hysteresis. If the PS measurement signal is higher than the

PS high threshold (PS_TH) the INT state is switched to active. If the PS measurement signal is

lower than the PS low threshold (PS_TL) the INT state is inactive. If once interrupt signal be-

comes active, INT status is kept active until measurement result becomes less than PS_TL reg-

ister value.

10 PS_TH & PS_TL (PS high & low threshold) are active as outside detection:

In case of „PS outside detection“ mode interrupt signal inactive means that measurement result

is within registered threshold level and interrupt signal active means measurement result is out

of registered threshold level.
