• Manufacturer Part Number: XC68HC705F32
• Description: MICROCONTROLLER
• Manufacturer: Motorola

15.3.3
In the direct addressing mode, the effective address of the argument is contained in a single byte
following the opcode byte. Direct addressing allows the user to directly address the lowest 256
bytes in memory with a single two-byte instruction.
