6809/6309 Mnemonic Lookup

You can lookup a single instruction by typing LD in the instruction field, which will show all load instructions. You can also lookup multiple instructions like LD,CMP.

You can also lookup mnemonics like LDX,LDY in the mnemonic field.

Description:

Load 32-bit Data into Accumulator Q [Q' <- IMM32 | (M:M+3)]

Documenation

This instruction loads either a 32-bit immediate value or the contents of a quad-byte value from memory (in big-endian order) into the Q accumulator. The Condition Codes are affected as follows.

• N The Negative flag is set equal to the new value of bit 31 of Accumulator Q.
• Z The Zero flag is set if the new value of Accumulator Q is zero; cleared otherwise.
• V The Overflow flag is always cleared.
