Function
DSW(210) outputs control signals to bits 00 to 04 of O, reads the specified number of digits (either 4-
digit or 8-digit, specified in C1) of digital switch data line data from I, and stores the result in D and D+1.
(If 4 digits are read, the result is stored in D. If 8 digits are read, the result is stored in D and D+1.)
DSW(210) reads the 4-digit or 8-digit switch data once every 16 cycles, and then starts over and contin-
ues reading the data. The One Round Flag (bit 05 of O) is turned ON once every 16 CPU Unit cycles.
