An example of high-speed RAM write with a window address-range specified is shown below.
The window address-range can be rewritten to consecutively and quickly by inserting two dummy writes
at the start of a row and three dummy writes at the end of a row, as determined by using the window
address-range specification bits (HSA1 to 0
=
“10”, HEA1 to 0
=
“00”).
Figure 35 Example of the High-Speed RAM write with a window address-range specification
Note1) The address set for the high-speed RAM write must be 00 or 11 according to the value of I/D0 bit.
Only RAM in the speicfied window address-range will be overwritten.
