Y-register (Y)
Y-register has 4 bits. It operates as a data pointer or a general-purpose register.
Y-register specifies and address (a
0
~a
3
) in a page of data memory, as well as it
is used to specify an output port. Further it is used to specify a mode of carrier
signal outputted from the REMOUT port. It can also be treated as a general-
purpose register on a program.
Accumulator (A
CC
)
The 4-bit register for holding data and calculation results.
Arithmetic and Logic Unit (ALU)
In this unit, 4bits of adder/comparator are connected in parallel as it's main
components and they are combined with status latch and status logic (flag.)
(1) Operation circuit (ALU) :
The adder/comparator serves fundamentally for full addition and data
comparison. It executes subtraction by making a complement by processing
an inversed output of A
CC
(A
CC
+1)
(2) Status logic :
This is to bring an ST, or flag to control the flow of a program. It occurs when
a specified instruction is executed in three cases such as overflow or
underflow in operation and two inputs unequal.
