4.2.7 SYSTEM RESET COMMAND

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”.
