Reset channel.
0 No special action.
1 Causes a software reset of the channel, clearing all its internal state. The details of the software reset
actions depend upon what the channel is doing when the bit is set:
If the R bit is set while the channel is requesting an EU assignment from the controller, the channel cancels its
request by asserting the release output signals. The channel then resets all its registers, clears the R bit, and
returns the channel state machine to the idle state.
If the R bit is set after the channel has been assigned an EU, the channel requests a write from the controller
to set the software reset bit of the EU. If a secondary EU has been reserved, the channel requests a write to
reset that EU as well. The channel next asserts the appropriate release signal to notify the controller that the
channel has finished with the reserved EU(s). The channel then resets all the registers, clears the RESET bit
and returns the channel state machine to the idle state.
Reserved. Set to zero.
Burst size. The SEC accesses long text-data parcels in main memory through bursts of programmable size:
0 Burst size is 64 bytes
1 Burst size is 128 bytes

Reserved. Set to zero.
Extend address enable. This bit determines whether the channel uses a 36-bit address bus or a 32-bit address
bus.
0 Channel’s address bus is 32 bits.
1 Channel’s address bus is 36 bits. (Not available in SEC 2.1)
0 Channel done writeback disabled.
1 Channel done writeback enabled.
Upon completion of descriptor processing, if the NT bit is set for global, or if the DN (done notification) bit is set
in the header word of the descriptor, then notify the host by writing back the descriptor header with the
writeback information shown in
descriptor header to determine if that descriptor has been completed.
