FOTA operation write address register. SOC can write to this register to preload address for FOTA write instead of having 8051 firmware to setup address. Writing this register causes an indirect write to MCU_DAT_ADDR0-MCU_DAT_ADDR3 ESFR registers that are used by the VBUSM initiator as address for the FOTA write operation. Preloading these ESFR registers through this register removes the burden from 8051 firmware and reduces 8051 code size.
