rwu undefined Specify the number of descriptor that forms the context
program.
3.2.37. IR ContextMatch
This register specifies the received channel in single- channel mode and the value to be compared with the
sync and tag sections in the received packet.
sync field is valid only when ” w” field contains ”11b” in the first descriptor. The chip discards the received
packet even if the tag information and the received packet’s channel match with the specified values as long
as the sync value is different.
cycleMatch field is valid only when IRContextControl.cycleMatchEnable bit is set. (However, in case IntE-
vent.cycleInconsistent bit is set, it is not valid.)

description
------------------------------------------
Specifying ”1” at this bit enables to receive the
isochronous packet that has the tag ”11b’.
undefined Specifying ”1” at this bit enables to receive the
isochronous packet that has the tag ”10b’.
undefined Specifying ”1” at this bit enables to receive the
isochronous packet that has the tag ”01b’.
undefined Specifying ”1” at this bit enables to receive the
isochronous packet that has the tag ”00b’.
undefined Specify the start time for the context program process.
undefined Specify the value to be compared with the sync on the
received isochronous packet.
undefined Specifying ”1” at this bit allows to receive isochronous
packet that has only upper 2- bit of sync field contains
”00b” and the tag field contains ”01b”.
5:0 channelNumber rw
undefined Specify the channel for the isochronous packet to be
received.
