Note 1 : The commands F1 and F2 settings become valid when the least four bits of C4 to C7 are input.

(The bits from D1 to D40 and from C0 to C3 are not necessary.)

Note 2 : If the dummy bit is needed for the reason of number of transfer bits, put it on the first bit side.

Note 3 : The command execution follows the contents of the C7 to C0 registers immediately before the LOAD

becomes "H".
