isochHeader
rsc undefined ”0” at this bit stores the received packet in the memory
removing the header and trailer data.
29
cycleMatchEnable rscu undefined ”1” at this bit indicates that the context program process
activates when the cycle timer reaches the time specified
in the cycleMatch.
28
multiChanMode rsc undefined ”1” at this bit, receives the isochronous packet on the
channel as set in the IRMultiChanMask register. (Multi-
channel mode)
”0” at this bit, receives the isochronous packet on the
channel as set in the IRContextMatch.channelNumber.
(Single- channel mode)
27
dualBufferMode rsc undefined “1” at this bit, stores the received packet with dual buffer
mode. (This bit is not available.)
15
run
rscu 0b
Specifying ”1” at this bit runs the context program
controller.
12
wake
rsu undefined Specifying ”1” at this bit wakes up the context program
controller to restart the process.
11
dead
ru
0b
This bit indicates ”1” when the context program controller
can not proceed the operation because an error occurred.
10
active
ru
0b
This bit indicates ”1” when the context program controller
is in- process.
7:5 spd
ru
undefined These bits indicate the transfer rate at the packet receive
4:0 eventcode
ru
undefined These bits contain the result of context program process.
3.2.36. IR DMA CommandPtr
This register specifies the start address of host memory where the first context program is contained and the
number of descriptor. Set this register when the ARContextControl.run bit and .active bit are cleared.
When the device is buffer- fill mode which means the context program is formed with 1 descriptor, set ”1h” at Z
field. When the device is packet- per- buffer mode, set ”1h” to ”8h” in the Z field because the context program
is formed with maximum 8 descriptors.
When an error occurred while processing the context program, the descriptorAddress field indicates the start
address in the host memory where the descriptor that was processed is contained. When the context pro-
gram is normally completed, the address field indicates the host memory start address where the last pro-
cessed descriptor is contained and Z field indicates ”0”.
