10.3.2
Start Address Register (STAR)
STAR is an 8-bit read/write register, for designating a transfer start address in the address space
(H'FF80 to H'FF9F) allocated to the 32-byte data buffer. The lower 5 bits of STAR correspond to
the lower 5 bits of the address. The extent of continuous data transfer is defined in STAR and in
the end address register (EDAR). If the same value is designated by STAR and EDAR, only 1 byte
of data is transferred.
Bits 7 to 5 are reserved; they are always read as 1, and cannot be modified.
Upon reset, STAR is initialized to H'E0.
