SERIAL MICROPROCESSOR INTERFACE BLOCK
The serial microprocessor uses a standard 3-pin serial port with CS, SCLK, and SDI for programming the LIU.
Optional pins such as SDO, INT, and RESET allow the ability to read back contents of the registers, monitor
the LIU via an interrupt pin, and reset the LIU to its default configuration by pulling reset "Low" for more than
10

:
If the R/W bit is set to "1", then this denotes a "READ" operation with the Microprocessor Serial Interface.
Conversely, if the R/W bit is set to "0", then this denotes a "WRITE" operation.
