Bruker DPP1 - Table 5.30: Bit Field Description; Table 5.31: Type of External Memory

Description
Technical Manual Version 001 BRUKER BIOSPIN 39 (55)
The MTYPE field identifies the memory type for the corresponding CE space. If
the MTYPE field selects a synchronous memory type (SBSRAM), the remaining
fields of the register have no effect.
External Memory at EMIF, Space CE0 5.4.9.3
The DSP is connected to an external synchronous SRAM. This memory chip is or-
ganized as 128K x 36 bit.
Table 5.30: Bit Field Description
Field Value Description
Write setup
1111
Number of clock cycles of setup time for address (EA), chip enable (CE),
and byte enables (BE 3..0) before the write strobe falls. For asynchro
-
nous read access, this is also the setup time of AOE before ARE falls.
Read setup
111111
Number of clock cycles of setup time for address (EA), chip enable (CE),
and byte enables (BE 3..0) before the read strobe falls. For asynchronous
read access, this is also the setup time of AOE before ARE falls.
Write strobe 111111 The write strobe width in number of clock cycles.
Read strobe 111111 The read strobe width in number of clock cycles.
Write hold
11
The number of clock cycles that address (EA) and byte strobes (BE 3..0)
are held after the write strobe rises. For asynchronous read access, this
is also the hold time of AOE after ARE rising.
Read hold
11
The number of clock cycles that address (EA) and byte strobes (BE 3..0)
are held after the read strobe rises. For asynchronous read access, this is
also the hold time of AOE after ARE rising.

Memory type definition:
8–bit wide SBSRAM
16–bit wide SBSRAM
32–bit wide SBSRAM
TA

Turn around time: Controls the number of ECLKOUT cycles between a
read and write, or between reads, to different CE spaces (asynchronous
memory types only).
