The DIT channel status (C) and user (U) data bits in register page 2 may be programmed after the DIT block has
powered up. To program these bits, disable buffer transfers by setting the BTD bit in control register 0x08 to '1'.
Then, select register page 2 using register address 0x7F. You can now load the necessary C and U data
registers for the intended application by writing the corresponding data buffer addresses. When you have
finished writing the C and U data, select register page 0 using register address 0x7F. Re-enable buffer transfers
by setting the BTD bit in control register 0x08 to '0'.
