Detailed Description

The ALT_DMA_CCR_OPT_* macro definitions are defined here to facilitate the dynamic microcode programming of the assembler directive:

DMAMOV CCR, [SB<1-16>] [SS<8|16|32|64|128>] [SA<I|F>]
            [SP<imm3>] [SC<imm4>]
            [DB<1-16>] [DS<8|16|32|64|128>] [DA<I|F>]
            [DP<imm3>] [DC<imm4>]
            [ES<8|16|32|64|128>]

with a DMAMOV instruction (see: alt_dma_program_DMAMOV()).

For example the assembler directive:

DMAMOV CCR SB1 SS32 DB1 DS32

would be dynamically programmed with the following API call:

alt_dma_program_DMAMOV( pgm,
                        ALT_DMA_PROGRAM_REG_CCR,
                        (   ALT_DMA_CCR_OPT_SB1
                          | ALT_DMA_CCR_OPT_SS32
                          | ALT_DMA_CCR_OPT_SA_DEFAULT
                          | ALT_DMA_CCR_OPT_SP_DEFAULT
                          | ALT_DMA_CCR_OPT_SC_DEFAULT
                          | ALT_DMA_CCR_OPT_DB1
                          | ALT_DMA_CCR_OPT_DS32
                          | ALT_DMA_CCR_OPT_DA_DEFAULT
                          | ALT_DMA_CCR_OPT_DP_DEFAULT
                          | ALT_DMA_CCR_OPT_DC_DEFAULT
                          | ALT_DMA_CCR_OPT_ES8
                        )
                      );

Each CCR option category should be specified regardless of whether it specifies a custom value or the normal default value (i.e. an ALT_DMA_CCR_OPT_*_DEFAULT.
