The serial microprocessor uses a standard 3-pin serial port with CS, SCLK, and SDI for programming the
transceiver. Optional pins such as SDO, INT, and RESET allow the ability to read back contents of the
registers, monitor the transceiver via an interrupt pin, and reset the transceiver to its default configuration by
pulling reset "Low" for more than 30ns. A simplified block diagram of the Serial Microprocessor is shown in
Figure 28.

The serial port requires 16 bits of data applied to the SDI (Serial Data Input) pin. The Serial Microprocessor
samples SDI on the rising edge of SCLK (Serial Clock Input). The data is not latched into the device until all 16
bits of serial data have been sampled. A timing diagram of the Serial Microprocessor is shown in Figure 29.

The serial microprocessor interface does
NOT
support "burst write" or "burst read" operations. Chip Select (active
