xe1202 ETC-unknow, xe1202 Datasheet - Page 14

• Manufacturer Part Number: xe1202
• Description: Low-power, Integrated Uhf Transceiver
• Manufacturer: ETC-unknow

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.
In addition, 16 bytes at addresses A[4:0] = 10000 to 11111 are reserved for test purpose
All the bits that are referred as “reserved” in this section should be set to “0”.
