Description
Host interface is in transfer cycle wait state
[Clearing conditions]
Host interface is performing transfer cycle processing
[Setting condition]
Description
No LCLK restart request
[Clearing conditions]
LCLK restart request issued
[Setting condition]
Bus idle, or transfer cycle not subject to processing is in progress
Cycle type or address indeterminate during transfer cycle
LPC hardware reset or LPC software reset
LPC hardware shutdown or LPC software shutdown
Forced termination (abort) of transfer cycle subject to processing
Normal termination of transfer cycle subject to processing
Match of cycle type and address
LPC hardware reset or LPC software reset
LPC hardware shutdown or LPC software shutdown
SERIRQ is set to continuous mode
There are no further interrupts for transfer to the host in quiet mode
In quiet mode, SERIRQ interrupt output becomes necessary while LCLK is
stopped
