bit command to “H” (ON) and “L” (OFF).
command can be transmitted irrespective of the state of MIACK signal.
(waiting for becoming to MIACK = “L” at the MIACK = “H”)
MICS = “H” after 24 bit command transmission.
The case where a program is started after program boot, and in restarting a program, it performs
ON/OFF of soft reset are performed by carrying out and transmitting the bit of the soft reset in a 24
Since data with which ON/OFF of soft reset follow a command is not required, it is made into
In addition, in order to return from a incorrect operation state, when turning ON soft reset, a 24 bit
The procedure of ON/OFF of soft reset is shown in Figure 5.
Transmission of 24 bit command

It is possible to transmit the command
data of soft reset ON at MIACK = “H”.
Soft reset ON: Bit = “1”.
Soft reset OFF: Bit = “0”.
