3. Applicable devices
S: "D .b" cannot be indexed with index registers (V and Z).
Explanation of function and operation
Four arrow switches are connected to the inputs
to
+3, a seven-segment display unit having the BCD
decoder is connected to the outputs
to
+7, and a numeric value is input to
.
1. 16-bit operation (ARWS)
actually stores a 16-bit binary value ranging from 0 to 9999, but the value is expressed in the BCD format in the
explanation below for convenience.
When the command input is set to ON, the ARWS instruction executes the following operation.
When the command input is set to ON, the ARWS instruction executes the following operation.
