Quiet/Continuous Mode Flag
Indicates the mode specified by the host at the end
of an SERIRQ transfer cycle (stop frame).
0: Continuous mode
[Clearing conditions]
1: Quiet mode
[Setting condition]
Specification by SERIRQ transfer cycle stop frame.
Start Frame Initiation Request Select
Selects whether start frame initiation is requested
when one or more interrupt requests are cleared, or
when all interrupt requests are cleared, in quiet
mode.
0: Start frame initiation is requested when all
1: Start frame initiation is requested when one or
Interrupt Enable Direct Mode
Specifies whether LPC channel 2 and channel 3
SERIRQ interrupt source (SMI, IRQ6, IRQ9 to
IRQ11) generation is conditional upon OBF, or is
controlled only by the host interrupt enable bit.
0: Host interrupt is requested when host interrupt
1: Host interrupt is requested when host interrupt
interrupt requests are cleared in quiet mode.
more interrupt requests are cleared in quiet mode.
