Remarks
DMA
OUT
pin
If externally detecting the timing of DMA execution, use the signal from this pin. It is
“
H
”
level during DMA transferring. This signal is valid in the memory expansion
and microprocessor modes.
SYNC
OUT
pin
If externally detecting the timing of OP code fetch, use the signal from this pin. This signal is valid in the memory expansion and microprocessor modes.
