1 Common instructions
(i) Store the same value for both master IC and slave IC.
(ii) The settings of master IC and slave IC are determined
(iii) The upper 16 bits are sent to the master IC, and the lower
during the initial setting.
When flag F5 is set to 1:
M66307 EXD is “H”
M66307 EXD is “L”
16 bits are sent to the slave IC. The IC that transmits data
first is determined by to which of FIFO or LIFO the output
setting command is set.
When 32-bit parallel data is stored three times, serial out-
put data is transmitted, as shown in the table, according to
the output format determined by the output setting com-
mand.
DREQ words, fixed beginning data
length, and output format are set.
Data from data bus is stored.
Data from data bus is stored.
Data is output to data bus.
Write mode is set.
Send mode is set.
Write mode is set.
Send mode is set.
