General Description
The HT82M32A/HT82M32B are designed as 2D, 3D
3/5-key PS/2 optical mouse controller. These have se-
www.DataSheetr4iaUl.cinotmerface to access the PixArt sensor PAN101,
PAN301, PAN3101 or the same compatible series sen-
sor. Refer to the datasheets for detailed register de-
scriptions of the PixArt sensors.
