PCF8593 power consumption

What is the nominal power dissipation of a PCF8593 versus input clock frequency when counting external transitions? The datasheet just says: varie#s with frequency. In 32khz clock mode, the nominal power is 1 uA. I am hoping it will be similar in counting mode with input frequency at 32khz or lower.

HI

Yes,we don't have spec under counter mode,they should be similar with clock mode.

Event counter mode: supply current dependant upon input frequency
