Configuration words for CH1~CH2
Configure the four analog input channels. There are 8 modes for each channel which can be
configured separately.
When CH1 is configured for mode 1 (H’0001) CR#2 must be set as H’0001. The default
setting = H’0000. CH1 example:
Mode 0 (H’0000): Voltage input (-10V ~ +10V).
Mode 1 (H’0001): Voltage input (-5V ~ +5V).
