The XF registers are accessed by first writing an 8-bit number of 0x10 to the FIFO, then a 32 bit value whose lower 16 bits are the address, and the upper 16 bits are the number of addresses to write to - 1. Following is one or more 32 bit datas. | The XF registers are accessed by first writing an 8-bit number of 0x10 to the FIFO, then a 32 bit value whose lower 16 bits are the address, and the upper 16 bits are the number of addresses to write to - 1.
