Product data sheet
7.1.2 Read N byte from slave device
7.1.3 Write to 18IM internal register
The host issues the read command by sending an S character followed by an I
slave device address, and the total number of bytes to be read from the addressed
I
command, the SC18IM700 will access the I
bytes from the addressed I
Note that the second byte sent is the I
bit (R) of this byte must be set to 1 to indicate this is an I
The host issues the internal register write command by sending a W character followed by
the register and data pair. Each register to be written must be followed by the data byte.
The frame is then terminated with a P character.
Remark: Write and read from the internal 18IM register is processed immediately as soon
as the intended register is determined by 18IM.
