Read Data from GRAM (R22h)
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.
When bit processing, such as a logical operation, is performed within the HD66760, only one read can be
processed since the latched data in the first word is used.
