The Terminal Address Register base +2B
16
The terminal address register is a read/write register that sets the last
address of a memory segment. It is used with the base address registers to
define the memory segment.
Address 7654321 0

Terminal address Base address
Terminal Address. The terminal address field specifies the last address in a
memory segment before returning to the base address.
Base Address. The Base Address (bit 0) is the most significant bit
(bit 18) of the memory segment’s base address.
The Base Address Registers base +2D
16
and base +2F
16
The base address registers are read/write registers that specify the beginning
of a memory segment. This is the address where the segment starts after
either being reset by the address count enable bit (bit 2) of the memory
control register, or after reaching the terminal address.

Base address 0: start address MSByte

Base address 1: start address LSByte
The most significant byte of the segment’s base address is store in the least
significant byte of register base +2D
16
. The least significant byte of the
base address is stored in the least significant byte of base +2F
16
. The data
written to these registers is held in a temporary register until it is loaded into
the actual address counter by clearing and then setting the address count
enable bit (bit 2) of the memory control register (base +21
16
).
