steal program issues a wait request immediately before the DMA operation for the
LCD (LCD DMA operation 1) and HDMA (HDMA operation 1) are asserted, these
operations must wait until the steal program is finished before they can be performed.
(LCD DMA is given a higher priority than HDMA in bus arbitration. This means that

of the order in which they are issued. )
HDMA operation is finished before the next LCD driver output is started.
of HDMA operation time must be set so that it does not interfere with LCD DMA
operation. Alternatively, the LHSYNC period should be adjusted to accommodate a
wait request by the steal program (80 times of transmission for debug clock:
LH_SYNCLK), although this slightly reduces the LCD display quality.

Figure 3.27.2 shows an example of data bus occupancy timing in debug mode. If the
sued for LCD DMA and HDMA while the steal program is running are processed in
Taking the above into account, it is necessary to ensure that each LCD DMA or
