Bit 16 - Asynchronous master reset (ARST)
The whole C3 can be reset using this bit. The reset is done asynchronously in Hardware
thus guaranteeing a well known state after its execution. A special Hardware block takes
care of correct timings for the reset sequence. It takes about 6 clock cycles for the Hardware
reset. The Internal Memory may not be cleared.
Bit 15 to 0 - Channel n status (CnS)
The status of each Channel is mirrored in these bits. These bits are the same ones as found
in the Instruction Dispatcher Status and Control Register (ID_SCR). See the Instruction
Dispatcher document section for more details. To know the status of the other 8 Channels
(Channels 8 to 15) you must use the Channel Status Register (SYS_STR).

Bit 16 ARST
Description
1’b1
Reset the whole C3.
1’b0
(Clearing conditions) This bit is cleared as a consequence of
the reset, so it is always read zero. Writing zero has no effect.
