When high-speed write mode is used, note the following.
1. The logical and compare operations cannot be used.
2. Data is written to RAM each four words. When an address is set, the lower two bits in the address must be set to
the following values.
*When ID0=0, the lower two bits in the address must be set to 11 and be written to RAM.
*When ID0=1, the lower two bits in the address must be set to 00 and be written to RAM.
3. Data is written to RAM each four words. If less than four words of data is written to RAM, the last data will not be
written to RAM.
4. When the index register and RAM data write (R22h) have been selected, the data is always written first. RAM
cannot be written to and read from at the same time. HWM must be set to 0 while RAM is being read.
5. High-speed and normal RAM write operations cannot be executed at the same time. The mode must be switched
and the address must then be set.
6. When high-speed RAM write is used with a window address-range specified, dummy write operation may be
required to suit the window address range-specification. Refer to the High-Speed RAM Write in the Window Address
section.
