Channel Index Area of the Serial Register
One channel (1 Kb) of the channel index area consists of the 40 bits of address data.

The Y address is represented by 8 bits and addressing is made with 00h to FFh.
(2) Start X address, stop X address
The X address is represented by 16 bits (valid 13 bits). If, for example, the serial register is
1Mb, the 1K-word X address space is addressed with 000h to 3FFh.
