6. Mode Register (MDR) (Accessed with RS = 1, Register Number = (B’100)
This register (Figure 32), containing 3 invalid bits (D7 to D5) and 5 valid bits (D4 to D0), selects a
system clock and type of LCD driving waveform. It must also be initialized after power-on since it
determines overall HD66108T operation like the FCR register. If the FFS 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 in section 3.1).
