MC9S12G Datasheet, PDF (1097/1160 Pages) Freescale Semiconductor, Inc – Ignores external trigger. Performs one conversion sequence and stops.

Electrical Characteristics
Table A-20. ATD Conversion Performance 5V range, RVA enabled
Supply voltage V_DDA =5.0 V, -40^oC < T_J < 150^oC. V_RH = 5.0V. f_ATDCLK = 0.25 .. 2MHz ¹
The values are tested to be valid with no PortAD/C output drivers switching simultaneous with conversions.
