DRAM Refresh Address Output Function
The LCTC outputs the address for DRAM refresh while CL1 is high, as shown in Figure 19. The 16 refresh
addresses per scanned line are output 16 times, from $00–$FF.
Skew Function
The LCTC can specify the skew (delay) for CUDISP, DISPTMG, CL2 outputs and MD inputs.
If buffer memory and character generator ROM cannot be accessed within one horizontal character display
period, the access is retarded to the next cycle by inserting a latch to memory address output and buffer
memory output. The skew function retards the CUDISP, DISPTMG, CL2 outputs, and MD inputs in the
LCTC to match phase with the display data signal.
By utilizing this function, a low-speed memory can be used as a buffer RAM or a character generator
ROM.
This function is controlled by pins SK0 and SK1 as shown in Table 7.
