1. An apparatus comprising:
a serial output communication terminal providing a serial communication; and
an interface circuit communicably connected to the serial output communication terminal and adapted to send an output serial data frame to a controller via the serial output communication terminal, wherein each output serial data frame includes a status phase and a data phase serially followed by at least one cyclic redundancy check (CRC) bit, which is serially followed by a fault bit, in which the fault bit indicates whether a fault is detected during sending of the output serial data frame, the fault bit is followed by a redundancy bit providing a redundant indication of whether a fault is detected, and the interface circuit includes:
control logic;
an input register;
a fault flag register; and
an output register.
