C-bus with interrupt
12. Static characteristics
[1]
The power-on reset circuit resets the I

POR
and sets all I/Os to logic 1 (with current source to V
DD
).
Each bit must be limited to a maximum of 25 mA and the total package limited to 200 mA due to internal busing limits.

The value is not tested, but verified on sampling basis.
