SBAS407A – DECEMBER 2006 – REVISED MAY 2007

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'.
