+To write to the DC, wait for the lowest '''Write Control''' bit to be set, then write a 8 bit value to any of the '''DC write registers'''. Writing 0xFF to a register triggers a 32-bit write using the '''Write Data''' register.
+
+To read from the DC, write an address to '''Read Address''' and wait for the lowest '''Read Control''' bit to be set. '''Read Data''' now contains the data read.
