Register 0x82300-0x823FF: A1SP CAS/Pattern Matching Configuration
Table
This table contains the configuration fields for automatic idle channel detection or
processor idle detection depending on the value of IDLE_CFG. The A1SP block
contains 8 lines of 32 channels (8 x 32 = 256 channels total per A1SP). The
function of these fields changes depending on whether IDLE_CFG indicates
CAS mode, Pattern Matching, or Processor Idle Detection mode for the
associated channel. The configuration field for each channel is composed of a
16 bit field (AUTO_CONFIG/PROC_CONFIG) and therefore each word contains
the status for 1 channel. The structure of the table is shown below.
LINE = OFFSET (MOD 256) / 32
CHANNEL (ADDRESS) = OFFSET (MOD 32)

AUTO_CONFIG_n/PROC_CONFIG_n
AUTO_CONFIG has two different formats. If IDLE_CFG = “10” (CAS mode)
it has one format. If IDLE_CFG = “11” it has a different format. If IDLE_CFG
= “01” the field uses the PROC_CONFIG_n format which is different than the
AUTO_CONFIG_n format.
AUTO_CONFIG/PROC_CONFIG should only be updated while IDLE_CFG =
“00”. Once AUTO_CONFIG/PROC_CONFIG is configured correctly, then
IDLE_CFG should be put into the desired mode.
The format follows the processor idle detection format shown below.
