Memory Configuration:
“000” = No external memory
“100” = Bank of 1 M words (max. 1 bank)
“101” = Banks of 512 K words (max. 2 banks)
“110” = Banks of 256 K words (max. 4 banks)
“111” = Banks of 128 K words (max. 4 banks)
All others = Reserved.
Memory Type:
‘0’ = Flow-through
‘1’ = Pipelined.
Parity Error Service Enable.
When this bit is set and either the LPPRTY_E bit or the HBPRTY_E bit is asserted at
7004h, the XMEMA_SRV bit is set in the Main Status Register at 0002h.
Always reads “0000_0000_000”.
Permanent Underrun Report. (Applies only to SDT mode.)
This register represents bits<15:0> of the 32-bit permanent underrun reports. Bit<15> cor-
responds to channel 15, bit<14> corresponds to channel 14, etc.
When an underrun occurs on a certain channel, the corresponding bit is set high; the
microprocessor can clear these bits by writing them to ‘0’.
