6. Horizontal Displayed Characters Register (R6, R7)
The horizontal displayed characters register (Figure 23) is composed of eight bits (R6, R7). It specifies the
number of characters displayed on one horizontal line, called the number of horizontal line, called the
number of horizontal displayed characters.
This register can specify even numbers only. In dual-screen modes (display modes 1, 6, and 16), the most
significant bit of this register is invalid. When writing into this register, shift (Nhd – 1) in the low-order
direction for one bit to cut off the least significant bit. Figure 24 shows how to write a value into the
register when Nhd = 90.
7. CL3 Pulse Width Register (R8)
The 4-bit CL3 pulse width register (Figure 25) specifies the high-level pulse width of the CL3 signal. In
TFT-type LCD modes, a data hold time is necessary and it is determined by the high-level pulse width of
the CL3 signal. The CL3 signal is output with the high-level pulse width specified by this register even
when the HD66841 is not in a TFT-type LCD mode.
