按上面的理解，对于GP 0 传输BT656模式，blankgen = 1,按照手册配置如下：
1. Configure the EPPI to operate in GP 0 FS mode by setting XFRTYPE = b#11 and FSCFG = b#00 in the
EPPI_CTL register.
ENUM_EPPI_CTL_NON656|
ENUM_EPPI_CTL_SYNC0
2. When receiving, configure the EPPI to trigger on internally or externally by setting the FLDSEL field
appropriately in the EPPI_CTL register. When transmitting, the trigger will always be internally generated.
ENUM_EPPI_CTL_FLDSEL_HI
*pREG_EPPI0_CTL = ENUM_EPPI_CTL_TXMODE |
ENUM_EPPI_CTL_NON656 |
ENUM_EPPI_CTL_SYNC0 |
ENUM_EPPI_CTL_INTCLK |
ENUM_EPPI_CTL_BLANKGEN|
ENUM_EPPI_CTL_FLDSEL_HI|
ENUM_EPPI_CTL_PACK_EN |
ENUM_EPPI_CTL_DLEN08;
这样配置对吗？
还需要配置下面的寄存器吗？
*pREG_EPPI0_LINE = ;
*pREG_EPPI0_FRAME = ;
*pREG_EPPI0_HCNT = ;
*pREG_EPPI0_VCNT = ;
*pREG_EPPI0_FS1_PASPL = ;
*pREG_EPPI0_FS1_WLHB = ;
*pREG_EPPI0_FS2_PALPF = ;
*pREG_EPPI0_FS2_WLVB = ;
3. Configure DMA to move the data to or from memory.
4. Enable DMA.
5. Enable EPPI.
请指点，谢谢各位！！！
