Abstract
An object of this invention is to enable a lock transaction to be carried out between apparatuses connected through a bus such as IEEE 1394 method with fewer data transmission processings. If a register conditionally writable is mounted on a desired apparatus connected through the serial communication bus, when it is intended to write into an apparatus having this register through the bus from other apparatus, a value estimated to be written in the register is obtained by a predetermined processing and then, that value and a value desired to be written into the register are instructed directly so as to control the write into the register.
