0000 ; FUNCTION NAME: CSD_UpdateGroupBaselines(BYTE bSnsGroup)
0000 ;
0000 ; DESCRIPTION: Updates baseline for a sensor group
0000 ;-----------------------------------------------------------------------------
0000 ; STACK USAGE: 3 BYTES
0000 ;
0000 ; ARGUMENTS:
0000 ; A => Sensor Group
0000 ; Sensor Group = 0 for the independent sensors group
0000 ; Sensor Group = 1 for the first slider group
0000 ; Sensor Group = 2 for the second slider group
0000 ;
0000 ; RETURNS:
0000 ; None
0000 ;
0000 ;
0000 ; SIDE EFFECTS:
0000 ; The A and X registers may be modified by this or future implementations
0000 ; of this function. The same is true for all RAM page pointer registers in
0000 ; the Large Memory Model. When necessary, it is the calling function's
0000 ; responsibility to perserve their values across calls to fastcall16
0000 ; functions.
