Triggering and terminating a soft reset
A soft reset is required before the system can start a program after program boot or restart a
program.
A 24-bit command with its soft reset bit set to "1" triggers a soft reset and a command with the bit
cleared terminates a soft reset.
When trigging or terminating a soft reset, drive /MICS high after transferring the 24-bit command
because no data needs to follow the command.
Figure 9 shows the procedure for trigging or terminating a soft reset.
(If MIACK = “H” , wait until MIACK = “L”)
