Abstract
Register write circuitry (250) writes to a plurality of data register bits (276) using a single register write operation by storing both designated address bits (276) and an address field (274) for addressing a predetermined data register. The designation address bits (276) designate predetermined bits (A.sub.4,A.sub.2,A.sub.2,A.sub.1) within data register (76) to which data was to be written. Writing data (274) only to predetermined bits (276) in a register write operation uses a single write enable command (272) in a programmable and selectable manner without performing a read-modify-write or requiring the storage of a bit image of the register.
