DATA MEMORY (RAM)
1 word of RAM is composed of 4 bits, but 1-bit manipulation
(with the SB j, RB j, and SZB j instructions) is enabled for the
entire memory area. A RAM address is specified by a data
pointer. The data pointer consists of registers Z, X, and Y. Set a
value to the data pointer certainly when executing an instruction
to access RAM (also, set a value after system returns from RAM
back-up).
Note
Register Z of data pointer is undefined after system is released
from reset.
Also, registers Z, X and Y are undefined in the RAM back-up.
After system is returned from the RAM back-up, set these
registers.
