Table 16.10 Serial Interrupt Transfer Cycle Frame Configuration
There are two modescontinuous mode and quiet modefor serialized interrupts. The mode
initiated in the next transfer cycle is selected by the stop frame of the serialized interrupt transfer
cycle that ended before that cycle.
In continuous mode, the host initiates host interrupt transfer cycles at regular intervals. In quiet
mode, the slave processor with interrupt sources requiring a request can also initiate an interrupt
transfer cycle, in addition to the host. In quiet mode, since the host does not necessarily initiate
interrupt transfer cycles, it is possible to suspend the clock (LCLK) supply and enter the power-
down state. In order for a slave to transfer an interrupt request in this case, a request to restart the
