Channel Index Area of the Serial Register
One channel (1 Kb) of the channel index area consists of the 40 bits of address data.
(1) Stop Y address
(2) Start X address, stop X address
Start X address (ST0 to ST12)
Stop Y address (SPY0 to SPY7)
Stop X address (ST0 to SP12)
The Y address is represented by 8 bits and addressing is made with 00h to FFh.
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.
