Table 46-4. TCON_CTRL1 field descriptions (continued)
Field
Description
V_REF_SEL
v_ref selector, see Section 46.4.2.3, Toggle generator, for use of v_ref signal.
0: select tcon_pulse0 output as v_ref
1: select tcon_pulse1 output as v_ref
2: select tcon_pulse2 output as v_ref
3: select tcon_pulse3 output as v_ref
4: select tcon_pulse4 output as v_ref
5: select tcon_pulse5 output as v_ref
6: select tcon_pulse0 output as v_ref, while reset vtgl_counter and vtgl[3] to 0 at rising edge of v_ref.
7: select tcon_pulse0 output as v_ref, while set vtgl_counter to 1 and reset vtgl[3] to 0 at rising edge of
v_ref.
Note: pulse generated must be vertical based for the toggle generator.
H_REF_SEL
h_ref selector, see Section 46.4.2.3, Toggle generator, for use of h_ref signal.
0: select tcon_comp0 output as h_ref.
1: select tcon_comp1 output as h_ref.
2: select tcon_comp2 output as h_ref.
3: select tcon_comp3 output as h_ref.
VLEN
maximum counter value for vtgl_counter in the toggle generator. see Section 46.4.2.3, Toggle generator,
for detailed functionality of this field.
DATA_INV_EN
1: Enable output data inversion
The input pixel (n) is compared with pixel (n-1). If more than half of the RGB data bits toggle, the pixel (n)
output will be inverted and the tcon_out[11] flags this data inversion to the gray scale reference.
tcon_out[11] =1 -> data_out is inverted, tcou_out[11] =0 -> data_out is not inverted. Intention of this
feature is for board level EMI reduction
0: Disable output data inversion
COLOR_DEPTH
Color depth of each color component
1: 8 bits
0: 6 bits, the 2 LSB’s are set to 2’b0
RGB_PADDING_EN RGB data padding enable
1: enable padding during blanking
0: disable padding during blanking
RGB_PADDING
RGB data driven during blanking.
1: all “1”
0: all “0“
RSDS_MODE
1: RSDS mode, output RSDS bit mapping
0: TTL mode, output TTL bit mapping
