Configuration Registers

The users may write the configuration registers (write only) directly by calling the sc5506a_RegWrite
function. The syntax for this function is sc5506a_RegWrite(deviceHandle, registerCommand,
instructWord). The instructWord takes a 64 bit-word. However, it will only send the required number of
bytes to the device. These registers are the same for USB, SPI, and RS-232. Table 5 summarizes the register
addresses (commands) and the effective bytes of command data.
