Description
SOFT_RESET Writing 1 to this bit generates an internal reset to all components except registers in VIU2 block. This bit
should be set by software when an error interrupt is detected, and it needs to be cleared by software to
release the software reset.
FORMAT_CTRL Output pixel data format control. See below or refer to Figure 47-20 for detailed definition. Here 32-bit means
MODE32BIT is set and 16-bit means MODE32BIT is cleared. RGB mode means RGB_EN is set and YUV
mode means RGB_EN is cleared. C means U or V. Dummy means “don’t care” data.
16-bit RGB mode:
3'b000: {R[7:3], G[7:2], B[7:3]};
3'b001: {G[4:2], B[7:2], R[7:3], G[7:5]};
32-bit RGB mode:
3'b000: {alpha, R, G, B};
3'b001: {alpha, B, G, R};
3'b010: {R, G, B, alpha};
3'b011: {B, G, R, alpha};
16-bit YUV mode:
3'b000: {C,Y};
3'b001: {Y,C};
32-bit YUV mode:
3'b000: {dummy, Y, U, V};
3'b001: {dummy, Y, V, U};
3'b010: {dummy, U, V, Y};
3'b011: {dummy, V, U, Y};
3'b100: {Y, U, V, dummy};
3'b101: {Y, V, U, dummy};
3'b110: {U, V, Y, dummy};
3'b111: {V, U, Y, dummy};
ERROR_CODE Error code. Signals errors that triggered error IRQ.
0000 : No error
0001 : DMA arm command given during vertical active, DMA_ACT does not accept the value on IPS bus.
0010 : DMA arm command given during vertical blanking when DMA_ACT is set.
0100 : Line too long
0101 : Too many lines in a field/frame
0110 : Line too short
0111 : Not enough lines in a field/frame
1000 : FIFO overflow
1001 : FIFO underflow
1010 : One bit ECC error
1011 : Two or more bits ECC error
others: Reserved
FIELD_EN Interrupt enable bit for FIELD_IRQ.
VSYNC_EN Interrupt enable bit for VSYNC_IRQ.
HSYNC_EN Interrupt enable bit for HSYNC_IRQ.
VSTART_EN Interrupt enable bit for VSTART_IRQ.
DMA_END_EN Interrupt enable bit for DMA_END_IRQ.
ERROR_EN Interrupt enable bit for ERROR_IRQ.
