When the host issues a Read Buffer command, the SC18IS600/601 will return the data in
the Read Buffer on the MISO pin. Note that the Read Buffer will be overwritten if an
additional ‘Read N bytes’ or a ‘Read after write’ command is executed before the Read
Buffer command.
When the host issues this command, the SC18IS600/601 will first write N data bytes to
the I
device.
Table 9.
The SPI configuration command can be used to change the order in which the bits of SPI
data byte are sent on the SPI bus. In the LSB first configuration (SPI configuration data is
0x81), bit 0 is the first bit sent of any SPI byte. In MSB first (SPI configuration data is
0x42), bit 7 is the first bit sent.
