2. Architecture
2.3. Data Memory (RAM)
Up to 16 nibbles (16 words × 1pages × 4bits) is incorporated for storing data.
The whole data memory area is indirectly specified by a data pointer (X,Y). Page
number is specified by zero bit of X register, and words in the page by 4 bits in
Y-register. Data memory is composed in 16 nibbles/page. Figure 2-2 shows the
configuration.

2.4. X-register (X)
X-register is consist of 2bit, X0 is not used, X1 is only used for selecting of D8 ~ D9
with value of Y-register

2.5. Y-register (Y)
Y-register has 4 bits. It operates as a data pointer or a general-purpose register.
Y-register specifies an address (A0~A3) 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.
2.6. Accumulator (ACC)
The 4-bit register for holding data and calculation results.
