Symbols list:
D - Destination device.
S - Source device.
m, n- Number of active devices, bits or an operational constant.
Additional numeric suffixes will be attached if there are more than one operand with the same
function e.g. D
1,S3 or for lists/tabled devices D3+0, S+9 etc.
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.
DPPPP - 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.
- An operand which cannot be indexed, i.e. The addition of V or Z is either invalid or will
have no effect to the value of the operand.
