CONTROL INTERFACE
Commands to the transmitters are sent serially. Data bits on pin SDI are shifted into the device upon the rising edge of the clock on pin SCK
whenever the chip select pin nSEL is low. When the nSEL signal is high, it initializes the serial interface. The number of bits sent is an integer
multiple of 8. All commands consist of a command code, followed by a varying number of parameter or data bits. All data are sent MSB first
(e.g. bit 15 for a 16-bit command). Bits having no influence (dont care) are indicated with X. The Power On Reset (POR) circuit sets default
values in all control and command registers.
The status information or received data can be read serially over the IRQ pin. Bits are shifted out upon the falling edge of CLK signal
