The System Reset Command (SRC) allows the host
controller to issue a System Soft Reset command.
Unlike other SPI commands, the SRC is only a single
byte command and does not operate on any register.

The command is started by pulling the CS pin low. The
SRC opcode is the sent, followed by a 5-bit Soft Reset
command constant of 1Fh. The SRC operation is
terminated by raising the CS pin.
Figure 4-7 shows a detailed illustration of the System
Reset Command sequence. For more information on
SRC’s Soft Reset, refer to Section 11.2 “System
Reset”.
