If the received address matches the host address in an LPC register (IDR, ODR, STR, TWR), the
host interface enters the busy state; it returns to the idle state by output of a state count 12
turnaround. Register and flag changes are made at this timing, so in the event of a transfer cycle
forced termination (abort) before state #12, registers and flags are not changed.
