:
Set a value of page boundary to use for the HwSBP2. The actual page boundary is as follows.
PageBoundary =2
Sets a page element number with which the HwSBP2 starts a processing.
When the HwSBP2Ctl.PtPresent:1, set a value equal to or less. than 0x17
When the HwSBP2Ctl.PtPresent:0, set a value equal to or less than 0x02.
If you read it, the page element number currently in process is indicated.
Indicates the number of remaining data bytes of the page element currently being processed by the HwSBP2.
This register is read-only.
Sets the speed code of 1394 bus to be used for data transfer by the HwSBP2.
SpeedCode:0 100Mbps
SpeedCode:1 200Mbps
SpeedCode:2 400Mbps
SpeedCode:3 Reserved
Sets the max. payload value to be used by the HwSBP2. The actual payload size is as follows.
Payload = 2
Since the max. payload size transferable at 400Mbps is 2048 bytes, set “9” or less for this register.
This is a register to set a transmit destination of the HwSBP2. Set a Bus ID (10 bits) and Node ID (6 bits).
Set a split timeout time of a transaction of the HwSBP2.
SplitTime.Second: Set a value in second.
SplitTime.CycleCount: Set a value in 125 s. (Set range: 0 to 0x1F3F) Setting of a value exceeding 0x1F3F
is not possible.
