3.8.2 Control Register 2
A1-Input
Pin A1 at 7701h (Bits 0-2), if 7701 (Bit 0 = “0”) Input then read Control at 7701h (Bit 2)
• If Control = “0” - General Purpose => Read state at 7701h (Bit 1) and report
• If Control = “1” - Analog to Digital Channel => Read channel at 7702h (2 bytes) and report
A1-Output
Pin A1 at 7701h (Bits 0-2), if 7701 (Bit 0 = “1”) Output then read Control at 7701h (Bit 2)
• If Control = “0” - General Purpose => Set state at 7701h (Bit 1) and report
• If Control = “1” - Analog to Digital Channel => Report Error in configuration
A2-Input
