This bit determines the output characteristics of the INT_REQ pin.
0: The output on the INT_REQ pin is high/low when the interrupt is active; the output is the opposite when the interrupt is inactive.
1: The output on the INT_REQ pin is high/low when the interrupt is active; the output is in high impedance state when the interrupt
is inactive. (default)
This bit determines the active level on the INT_REQ pin for an active interrupt indication.
0: Active low. (default)
1: Active high.
This bit indicates the validity changes (from ‘valid’ to ‘invalid’ or from ‘invalid’ to ‘valid’) for the corresponding INn; i.e., whether
there is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the corresponding INn bit (b7~0, 4AH). Here n is any one of 8 to 1.
0: Has not changed.
1: Has changed. (default)
This bit is cleared by writing a ‘1’.
