25 Description
26 -----------
27
28 The Freescale MC13783 and MC13892 are Power Ma
29 Among other things they contain a 10-bit A/D c
30 (MC13783) resp. 12 (MC13892) channels which ca
31 A/D converter has a resolution of 2.25mV.
32
33 Some channels can be used as General Purpose i
34 a chip internal scaling applied .
35
36 Currently the driver only supports the Applica
37 the General Purpose inputs and touchscreen.
