Figure 2–9. Relationship Between SFLAG/NFLAG, BLANK, and SCLK
If SFLAG/NFLAG is designed as an R-S latch set by split shift register transfer timing and reset by BLANK
going high, the delay from BLANK high to SFLAG/NFLAG low cannot exceed one-half of one SCLK cycle;
otherwise, the SCLK generation logic may fail.
If the SSRT function is enabled but SFLAG/NFLAG is held low, SCLK runs as if the SSRT function is
disabled. The SFLAG/NFLAG input is not qualified by the BLANK signal and needs to be held low whenever
an SSRT SCLK pulse is not desired. Refer to Section 2.3.1 and Figures 2–2 through 2–8 for more system
details.
2.9.2
Special Nibble Mode
Special nibble mode is enabled when the SNM bit (bit 3 in the general control register) is set to 1 and the
SSRT bit (bit 2 in the general control register) is reset to 0 (see Section 2.11). Special nibble mode provides
a variation of the 4-bit pixel mode with a 16-bit bus width. While all 32 inputs (P<0:31>) are connected as
4 bytes, the 16-bit data bus is composed of the lower or upper nibble of each of the 4 bytes, depending on
the level of the SFLAG/NFLAG input. The pixel data is distributed to 16-bit data bus as shown in Table 2–7.
Table 2–7. Pixel Data Distribution in Special Nibble Mode
SNM BIT = 1, SSRT BIT = 0
SFLAG/NFLAG = 1
P<7:4>
P<15:12>
P<23:20>
P<31:28>
SFLAG/NFLAG = 0
P<3:0>
P<11:8>
P<19:16>
P<27:24>
The SFLAG/NFLAG value is not latched by the TLC34075A. Therefore, it should stay at the same level
during the whole active display period, changing levels only during the BLANK signal active time. Refer to
Figure 2–10, which is similar to Figure 2–2 except that the BLANK signal timing reference to SFLAG/NFLAG
is explained. The SFLAG/NFLAG input has to meet the setup time and hold the data long enough to ensure
that no pixel data is missed.
Special nibble mode operates at the line frequency when BLANK is active. However, the typical application
of this mode is double frame buffers with pixel data width of 4 bits. While one frame buffer is being displayed
on the monitor, the other frame buffer can be used to accept new picture information. SFLAG/NFLAG is used
to indicate which frame buffer is being displayed.
SNM and SSRT must be mutually exclusive. Unpredictable operation occurs if both the SNM and SSRT bits
are set to 1. The mux control register should be set up as shown in Table 2–6 (see Section 2.4.5). However,
the SNM bit takes precedence over the other mux control register selections. In other words, if the mux
control register is set up for another mode but special nibble mode is still enabled in the general control
register, the input multiplex circuit takes whatever SCLK divide ratio the mux control register specifies and
performs the nibble operation, causing operational failure.
