PM2329 ClassiPI Network Classification Processor Datasheet
Switching Between Sequencing Types
Sequencing can switch from OCC Sequencing to E-RAM Sequencing or vice versa, when a new sequence
is initiated following a Halt condition. The processor writes to the AOCC register to initiate a sequence,
selecting the type of sequencing desired by choice of AOCC bit 63, regardless of the previous state of bit
63.
When the hardware is in the "WAIT" state (that is, after completing an OC sequence), the PM2329
interprets a processor write to the AOCC as follows:
If AOCC[63] =
1
, the PM2329 initiates E-RAM sequencing, jumping to the specified C-word
address.
If AOCC[63] =
0
and AOCC[55:48] =
00000000
, the PM2329 terminates sequencing.
If AOCC[63] =
0
and AOCC[55:48] Not=
00000000
, the PM2329 initiates OCC sequencing as
specified by the AOCC[55:48] value.
When the hardware is in the "BREAK" state (that is, after any OC except the last one), the PM2329
interprets a processor write to the AOCC as follows:
If AOCC[63] =
1
, the PM2329 continues the next OC.
If AOCC[63] =
0
and AOCC[55:48] =
00000000
, the PM2329 terminates sequencing.
If AOCC[63] =
0
and AOCC[55:48] Not=
00000000
, the PM2329 continues with the next OC.
