2.8.18 Command Register F220h (R/W)

Command can be issued by two following methods, and user may select one way or the other to issue appropriate command;

1.Write command into Command Register when INT is at ready state. INT will automatically turn to busy state as command is issued. Once the desired operation is completed, INT will go back ready state.

2.Write 0000h to INT bit of Interrupt Status Register, and then write command into Command Register. Once the desired operation is com- pleted, INT will go back to ready state.

(00F0h and 00F3h may be accepted during busy state of some operations. Refer to the right most column of the command register table below.)

F220h, default = 0000h
