The procedure in Table 12-13 configures the transmit frame format unit of the MCASP module for a DIT-transmission.
Step | Register/Bit Field/Programming Model | Value |
---|---|---|
Configure the slot size to 32 bits. | MCASP_XFMT[7-4] XSSZ | 0xF |
IF: the data to transmit is left- aligned | Software test condition | |
Set data mask in the range 0xFFFF FF00 – 0xFFFF 0000. | MCASP_XMASK[31-0] XMASK | 0x-(1) |
Rotate data right by a multiple-of-4- bit positions. | MCASP_XFMT[2-0] XROT | 0x-(1) |
ELSE | ||
Set data mask in the range 0x00FF FFFF– 0x0000 FFFF. | MCASP_XMASK[31-0] XMASK | 0x-(1) |
Rotate data right by 0-bit positions. | MCASP_XFMT[2-0] XROT | 0x0 |
ENDIF | ||
Select to write data to active serializers transmit buffers using peripheral (CFG) or DATA port | MCASP_XFMT[3] XBUSEL | 0x- |
