16.4.7
A host interrupt request can be issued from the LPC interface by means of the SERIRQ pin. In a
host interrupt request via the SERIRQ pin, LCLK cycles are counted from the start frame of the
serialized interrupt transfer cycle generated by the host or a supporting function, and a request
signal is generated by the frame corresponding to that interrupt. The timing is shown in figure
16.10.
The serialized interrupt transfer cycle frame configuration is as follows. Two of the states
comprising each frame are the recover state in which the SERIRQ signal is returned to the 1-level
at the end of the frame, and the turnaround state in which the SERIRQ signal is not driven. The
recover state must be driven by the host or slave processor that was driving the preceding state.
