interrupt. Output (open collector). Active Low. On the
IA82527, two pins can provide the interrupt (int_n)
output; however, depending on the setting of the MUX
bit in the CPU Interface Register (02H), only one of the
pins will serve as the source of int_n as follows:
master in slave out. Output (open drain). Serial
Interface Mode. When the IA82527 is configured to
operate with a serial interface, miso is the serial data
output.
