The SSP is capable of block transfers as a SLAVE to and from both
DATA space and CSR space. In DATA space, the SSP will generate
SS=6 when writing more than 512K (or 1M, 2M) words is attempted. In
CSR space, the SSP will generate SS=6 when writing more
than 4K (64K with EPM) words into program memory or
512K to data memory is attempted. The SSP will respond to block
(MS=1) or pipeline (MS=3) transfers
As a MASTER, the SSP is capable of block transfers to and from its DATA memory only. There are 3 basic block read instructions and 1 block write instruction. The block instructions can be preceded by a secondary address or a primary and secondary address. See section on FASTBUS Instructions.
