(3) Toggle Operation Flowchart
(4) Toggle Operation Instructions
1
Common instructions
(i) Set the operation mode by using mode inversion com-
mand or toggle input (TOG).
(ii) When setting operation mode with toggle input (TOG)
in the DREQ mode (flag F4 = 1), do not use the one-line
fixed data setting command.
(iii) The settings of master IC and slave IC are determined
during the initial setting.
When flag F6 is set to 1:
M66307 EXD is “H”
Slave IC
M66307 EXD is “L”
Master IC
(iv) After a reset and the first mode setting, slave IC is in the
send mode. However, transmission is impossible be-
cause there is no data in the line memory.
New data is written in this stage.
(v) It is impossible to control mode inversion by using opera-
tion mode setting command and extended toggle input
(TOG) together.

When CLK IN is used:
(i) Toggle operation is feasible when the circuit is connected
as shown in Fig. 12.

When
φ
IN is used:
(i) Toggle operation is feasible when the circuit is connected
as shown in Fig. 13.
(ii) At the initial setting, set clock input to CLK IN.
φ
IN cannot be selected.
(iii) Divider clock output is not feasible.
