DO (pin 32) Operation (only in serial mode)
Figure 4 shows the changes in the DO signal when data is not output by the CPU. When the output data is ready, DO
goes low and returns to the high level about 6 ms later. The data becomes invalid about 9 ms after either DO or INT-R
goes low, and data can still be read even after DO goes high. (Horizontal data (only horizontal data) can be read out for a
period of about 18 ms.)
The reason DO goes high after 6 ms is so that the CPU interface can handle applications where the CPU does not use the
interrupt port.
When DO is low, there is guaranteed to be a window of at least 3 ms during which data can be transferred. (This eases
software operation.) INT-R can be used as an edge trigger interrupt. Note that the 68 μs period prior to the leading edge
of INT-R is the LSI's output buffer write period, and that data read during this period is not guaranteed.
