This reg is always read 0x00 (even after writing 0x01).

Writing 0x01 to this register will result in a general reset

operation to the ZR36505, leaving all registers in their

default values.

The serial bus consists of a clock signal and a data signal, which relate to the ZR36505 as a

bus slave (where the ZR36504 is used as the bus master).

The ZR36505 device address is 0xEE for a Write operation, and 0xEF for a Read

operation.
