B4920 analog inputs read 8.6-8.9 volts instead of 10 volts for full scale

Issue

analog input shows 8.6-8.9 volts instead of 10 volts

Environment

B4920

Cause

The pull up resistor when disabled will drop the top end voltage slightly

Resolution

Pull up resistor on = 10 volts top scale

Pull up resistor off = 8.6-8.9 volts top scale (by design)
