Data Sheet

XE1202

When the serial interface is not used for read or write operations, both SCK and SI should be set to “1”. Except in

read mode, SO is set to “0”.

5.2 Configuration and Status registers

XE1202 has a series of configuration registers programmable through the serial control interface described above.

Their name, size, address and description are listed in the table below. The size of these registers is 1, 2, 3, or 4

bytes. Their byte address is 5 bit address, A[4:0]. In addition, there is one register, DataOut, from which users can

read various transceiver status information.
