0x0140 STATUS RO

Bit 0: Status bit.

1 = advanced test pattern generator is processing a video field, 0 otherwise.

Bit 1 : Pending register updates bit

Lite mode is off only.

Any writes to registers excluding pattern X registers cause the IP to raise pending register updates bit, to indicate outstanding changes yet to be committed. Refer to register Pattern X Select for more information.

The IP lowers this bit at the next field boundary after a write to the COMMIT register.

0x0144 FIELD_COUNT RO Read this register to determine the output field count. The value in this register is reset each time the IP stops.
0x0148 CONTROL RW

Bit 0: Go bit.

Write 0 to this register to stop the test pattern generator at the end of the current frame. Write 1 to this register to start or restart output generation. This register initializes to 0 at start-up and no output fields are generated until after a write of 1 to this register.

Writes to this register apply immediately, without needing to further write to COMMIT.

0x014C COMMIT RW The IP holds any changes pending to registers (excluding those prefixed with PATTERN_X_) until you send a write to this register. The value you write is unimportant.
0x0150 FIELD_WIDTH RW

Write to this register to set the width of outgoing video fields. If the output chroma sampling is 4:2:2 or 4:2:0, the width should be a multiple of 2.

The width of the canvas that applies to pattern 0. If the widths and offsets of other patterns (set via LAYER_N registers) cause that pattern to go out of the canvas boundaries, the IP does not show that pattern.

0x0154 FIELD_HEIGHT RW

Use this register to set the height for outgoing video fields. If the output chroma subsampling is 4:2:0, the height should be a multiple of 2.

The height of the canvas that applies to pattern 0. If the height and offsets of other patterns (set via LAYER_N registers) cause that pattern to go out of the canvas boundaries, the IP does not shows that pattern.

0x0158 FIELD_INTERLACE RW

Use this register to set the interlace output behavior for the first outgoing field. The value you write corresponds to the interlace identifier nibble of outgoing image information packets in full mode.

Values 0 to 7 produce progressive outputs.

Values 8 to 1 cause the field sequence to restart with F0.

Values 12 to 15 cause the field sequence to restart with F1.
0x015C + (n-1) *0x14 LAYER_N_WIDTH RW

Use this register to set the width of layer or pattern n (excluding pattern 0).

24
0x0160 + (n-1) *0x14 LAYER_N_HEIGHT RW

Use this register to set the height of layer or pattern n (excluding pattern 0).

24
0x0164 + (n-1) *0x14 LAYER_N_ALPHA RW Use this register to set the alpha value of layer or pattern n (excluding pattern 0). .
0x0168 + (n-1) *0x14 LAYER_N_H_OFFSET RW

Use this register to set the horizontal offset of layer or pattern n (excluding pattern 0).

24
0x016C + (n-1) *0x14 LAYER_N_V_OFFSET RW

Use this register to set the vertical offset of layer/pattern n (excluding pattern 0).

24
0x01E8 PATTERN_X_SELECT RW

Write to this register with values 0 to 7 to apply all pattern X registers to the given pattern number.

Only the registers that apply to the selected pattern have an effect.

Pattern configuration registers

The following sets of registers have different semantics according to the different types of test patterns, and they may share addresses. When you write a pattern number “X” to PATTERN_X_SELECT, only the registers that correspond to the test pattern type of pattern X have an effect.

Ensure you write to all registers specific for a type of pattern before committing via PATTERN_X_SELECT; values from previous writes may persist in registers otherwise, leading to unwanted behavior.

Table 78.  Advanced Test Pattern Generator IP Bars Pattern Registers

0x01F8 PATTERN_X_ZONE_FINE_FACTOR

WO

The value of this register acts as a fine tune scaling factor of the zone plate.

It is a 16-bit unsigned fixed-point number, with 8 bits fractional part.
