18.9.3 ADC Data Register Low
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
In left justified mode, this 8-bit result register holds the two LSBs of the
10-bit result. All other bits read as 0. This register is updated each time
a single channel ADC conversion completes. Reading ADRH latches the
contents of ADRL until ADRL is read. Until ADRL is read all subsequent
ADC results will be lost.
In right justified mode, this 8-bit result register holds the eight LSBs of
the 10-bit result. This register is updated each time an ADC conversion
completes. Reading ADRH latches the contents of ADRL until ADRL is
read. Until ADRL is read all subsequent ADC results will be lost.
