According to the key-in sequence (ON) of these input points, it is possible to enter 4 or 8decimal numbers into the registers specified by D.• When input control "EN" = 1, this instruction will monitor the10 input points starting from IN and put the correspondingnumber into D register while the key were depressed. It willwait until the input point has released, then monitor the next"ON" input point, and shift in the new number into D register(high digit is older than low digit ) . For the 16-bit operand, Dregister can store up to 4 digits, and for the 32-bit operand 8digits may be stored. When the key numbers full fill the Dregister, new key-in number will kick out the oldest keynumber of the D register. The key-in status of the 10 inputpoints starting from IN will be recorded on the 10corresponding coil starting from KL. These coils will set to 1while the corresponding key is depressed and remainunchanged even if the corresponding key is released. Untilother key is depressed then it will return to zero. As long asany input point is depressed (ON), then the key-in flag KPRwill set to 1. Only one of IN0~IN9 key can be depressed atthe same time. If more than one is pressed, then the firstone is the only one taken.
