3WRW: Initiates a 3-wire write or read operation. The write command uses the memory address
found in the 3-wire ADDRESS register (Table 02h, Register F9h) and the data from the 3-wire WRITE
register (Table 02h, Register FAh). This bit clears itself at the completion of the write operation.
The read command uses the memory address found in the 3-wire ADDRESS register (Table 02h,
Register F9h). The address determines whether a read or write operation is to be performed. This
bit clears itself at the completion of the read operation.
0 = (Default) Reads back as 0 when the write or read operation is completed.
1 = Initiates a 3-wire write or read operation.
3WDIS: Disables all automatic communication across the 3-wire interface. This includes all
updates from the LUTs, APC loop, and status registers. The only 3-wire communication is with the
manual mode of operation.
0 = (Default) Automatic communication is enabled.
1 = Disables automatic communication.

This byte is used during manual 3-wire communication. When a manual read or write is initiated, this register
contains the address for the operation.
