Abstract:
1. A register configuration control device comprising: a central processing unit that transmits first register configuration value information comprising a first register configuration value indicative of a value to be written into a register and first address information indicative of a register address, or second register configuration value information comprising a second register configuration value and second address information indicative of an address of at least one temporary storage section, the second register configuration value comprising a third register configuration value indicative of a value to be written into a register and third address information indicative of a register address, via a data bus and an address bus; a first selection section that receives the first register configuration value information or the second register configuration value information from said central processing unit, and the third register configuration value information from the at least one temporary storage section, and selects one transmission destination according to a predetermined priority to output corresponding register configuration value information; a second selection section that is operable when the first register configuration value information or the third register configuration value information is output from said first selection section, to select a transmission destination to which the first register configuration value information is to be sent, from at least one first transmission destination based on address information contained in the register configuration value information output from said first selection section, and send the first register configuration value information to the selected transmission destination, or when the second register configuration value information is output from said first selection section, to select a transmission destination to which the second register configuration value information is to be sent, from at least one second transmission destination based on the second address information, and send the second register configuration value information to the selected transmission destination; and at least one temporary storage section that is included in each of the at least one second transmission destination, said at least one temporary storage section temporarily storing the third register configuration value and the third address information contained in the second register configuration value sent from said second selection section as the third register configuration value information, and reading out and outputting the third register configuration value information in predetermined timing.
