Limitations
When the leftmost digit of C is 0, the rightmost two digits of C must each be be-
tween 0 and 3.
When the leftmost digit of C is 1, the rightmost two digits of C must each be be-
tween 0 and 1.
All result words must be in the same data area.
Description
Depending on the value of C, MLPX(76) operates as a 4-bit to 16-bit decoder or
an 8-bit to 256-bit decoder.
4-bit to 16-bit Decoder
MLPX(76) operates as a 4-bit to 16-bit decoder when the leftmost digit of C is 0.
The hexadecimal value of the digits in S are used to specify bits in up to 4 result
words. The specified bit in each result word is turned on, and the other 15 bits in
each word are turned off.
When the execution condition is OFF, MLPX(76) is not executed. When the
execution condition is ON, MLPX(76) converts up to four, four-bit hexadecimal
digits from S into decimal values from 0 to 15, each of which is used to indicate a
bit position. The bit whose number corresponds to each converted value is then
turned ON in a result word. If more than one digit is specified, then one bit will be
turned ON in each of consecutive words beginning with R. (See examples, be-
low.)
Control Word
The digits of C are set as shown below. Set the leftmost digit of C to 0 to specify
4-bit to 16-bit decoding.
Specifies the first digit to be converted (0 to 3)
Number of digits to be converted (0 to 3)
0: 1 digit
1: 2 digits
2: 3 digits
3: 4 digits
Not used. Set to 0.
A value of 0 specifies 4-bit to 16-bit decoding.
Digit number:
