DJM — Result Register Data Justification Mode
exited, the ATD module powers up and continues operation. The
module is not reset; the register file is not reinitialized; the conversion
sequence is not restarted.
When the module comes out of wait, it is recommended that a

started.
For 10-bit resolution, left justified mode maps a result register into
data bus bits 6 through 15; bit 15 is the MSB. In right justified mode,
the result registers maps onto data bus bits 0 through 9; bit 9 is the
MSB.
For 8-bit resolution, left justified mode maps a result into the high byte
(bits 8 though 15; bit 15 is the MSB). Right justified maps a result into
the low byte (bits 0 through 7; bit 7 is the MSB).
