LPC Busy
Indicates that the host interface is processing a transfer
cycle.
0: Host interface is in transfer cycle wait state
•
•
[Clearing conditions]
•
•
•
•
1: Host interface is performing transfer cycle processing
[Setting condition]
•
LCLK Request
Indicates that the host interface's SERIRQ output is
requesting a restart of LCLK.
0: No LCLK restart request
[Clearing conditions]
•
•
•
•
1: 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
