Read Data from GRAM (R22h)
Figure 24 Read Data from GRAM Instruction
RD15–0:
Read 16-bit data from the GRAM. When the data is read to the microcomputer, the first-word
read immediately after the GRAM address setting is latched from the GRAM to the internal read-data
latch. The data on the data bus (DB15–0) becomes invalid and the second-word read is normal.
