5. Control Register (FCR) (Accessed with RS = 1, Register Number = (B’011)
This register (Figure 31), containing eight bits, has a variety of functions such as specifying the method
for accessing RAM, determining RAM valid area, and selecting the function of the LCD driving signal
output pins. It must be initialized as soon as possible after power-on since it determines the overall
operation of the HD66108T. The PON bit may have to be reset afterwards. If the DUTY bits are rewritten
after initialization at power-on (if values other than the initial values are desired), the display memory
will not preserve data; the display memory must be set again after a time period of t
CL1
or longer. For
determining t
CL1
, refer to equation 1 (Section 3.1).
