Data memory used in program. Data is
handled in 16-bit units (one word).
This is a shared data memory which is
used within the MEWNET link system.
Data is handled in 16-bit units (one word).
Data memory for storing a target value of a
timer and an initial value of a counter.
Stores by timer/counter number.
Data memory for storing the elapsed value
during operation of a timer/counter. Stores
by timer/ counter number.
Data memory used in program. Data is
handled in 16-bit units (one word).
Data memory for storing specific data.
Various settings and error codes are
stored.
Index register (I) 14 words (I0 to ID) Register can be used as an address of
memory area and constants modifier.
