D - Destination device.
S - Source device.
m, n- Number of active devices, bits or an operational constant.

MSB - Most Significant Bit, sometimes used to indicate the mathematical sign of a number, i.e.
positive = 0, and negative = 1.
LSB - Least Significant Bit.
Instruction modifications:
PPP - An instruction operating in 16 bit mode, where PPP identifies the instruction
mnemonic.
PPPP - A 16 bit mode instruction modified to use pulse (single) operation.
DPPP - An instruction modified to operate in 32 bit operation.
DPPP - A 32 bit mode instruction modified to use pulse (single) operation.
 - A repetitive instruction which will change the destination value on every scan unless
modified by the pulse function.
