ADICLK — ADC Input Clock Select Bit
MODE1 and MODE0 — Modes of Result Justification
15.7.3 ADC Data Register 0 (ADRH0 and ADRL0)
The ADC data register 0 consist of a pair of 8-bit registers: high byte (ADRH0), and low byte (ADRL0).
This pair form a 16-bit register to store the 10-bit ADC result for the selected ADC result justification mode.
In 8-bit truncated mode, the ADRL0 holds the eight most significant bits (MSBs) of the 10-bit result. The
ADRL0 is updated each time an ADC conversion completes. In 8-bit truncated mode, ADRL0 contains no
interlocking with ADRH0. (See
Freescale Semiconductor
ADICLK selects either bus clock or CGMXCLK as the input clock source to generate the internal ADC
clock. Reset selects CGMXCLK as the ADC clock source.
If the external clock (CGMXCLK) is equal to or greater than 1MHz, CGMXCLK can be used as the
clock source for the ADC. If CGMXCLK is less than 1MHz, use the PLL-generated bus clock as the
clock source. As long as the internal ADC clock is at f
MODE1 and MODE0 selects between four modes of operation. The manner in which the ADC
conversion results will be placed in the ADC data registers is controlled by these modes of operation.
Reset returns right-justified mode.
