7.5 Fast Burst RAM Write Function
The EM65570 has a built-in fast burst RAM write function. This function allows data
transfer of 32 bits thus requiring only half of the access time needed for common
standard RAM write function (16-bit data bus). The burst RAM write function is suitable
for frequent data rewriting such as color animation display.
Fast Burst RAM Write Function works more efficiently in horizontal RAM data writing
mode, that is, RDWS[2]=0
