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 power down
mode).
RAM includes the area for LCD.
When writing “1” to a bit corresponding to displayed segment, the
segment is turned on.
Table 2 shows the RAM size. Figure 12 shows the RAM map.
• Note
Register Z of data pointer is undefined after system is released
from reset.
Also, registers Z, X and Y are undefined in the power down mode.
After system is returned from the power down mode, set these reg-
isters.
