SWD0–SWD3: Stopwatch timer data 1/1,000 sec (FF7DH)
Data (BCD) of the 1/1,000 sec column of the capture buffer can be read out.
The hold function of the capture buffer works by reading this data.
These 4 bits are read-only, and cannot be used for writing operations.
At initial reset, the timer data is set to "0".
SWD4–SWD7: Stopwatch timer data 1/100 sec (FF7EH)
Data (BCD) of the 1/100 sec column of the capture buffer can be read out. These 4 bits are read-only, and
cannot be used for writing operations.
At initial reset, the timer data is set to "0".
SWD8–SWD11: Stopwatch timer data 1/10 sec (FF7FH)
Data (BCD) of the 1/10 sec column of the capture buffer can be read out. These 4 bits are read-only, and
cannot be used for writing operations.
At initial reset, the timer data is set to "0".
Note: Be sure to data reading in the order of SWD0–3
→ SWD4–7 → SWD8–11.
