Table 592. Summary of ADC registers
[1]
The A/D Control Register provides bits to select A/D channels to be converted, A/D timing,
A/D modes, and the A/D start trigger.
Name
AD0DR3

AD0DR5
AD0DR6
AD0DR7
Selects which of the AD0.7:0 pins is (are) to be sampled and converted. For AD0, bit 0
selects Pin AD0.0, and bit 7 selects pin AD0.7. In software-controlled mode, only one of
these bits should be 1. In hardware scan mode, any value containing 1 to 8 ones. All
zeroes is equivalent to 0x01.
The APB clock (PCLK) is divided by (this value plus one) to produce the clock for the A/D
converter, which should be less than or equal to 4.5 MHz. Typically, software should
program the smallest value in this field that yields a clock of 4.5 MHz or slightly less, but in
certain cases (such as a high-impedance analog source) a slower clock may be
desirable.
Conversions are software controlled and require 11 clocks.
The AD converter does repeated conversions at the rate selected by the CLKS field,
scanning (if necessary) through the pins selected by 1s in the SEL field. The first
conversion after the start corresponds to the least-significant 1 in the SEL field, then
higher numbered 1 bits (pins) if applicable. Repeated conversions can be terminated by
clearing this bit, but the conversion that’s in progress when this bit is cleared will be
completed.
Important: START bits must be 000 when BURST = 1 or conversions will not start.
Reset Value reflects the data stored in used bits only. It does not include reserved bits content.
