2.7Clock Source Setting

The programmable interval timer 8254 is used in the PCI-9112. It provides 3 independent 16-bit programmable down counters. The input of counter 2 is connected to a precision 2MHz oscillator for internal pacer. The input of counter 1 is cascaded from the output of counter 2. The channel 0 is free for user's applications. There are two selections for the clock source of channel 0 : the internal 2MHz clock or the external clock signal from connector CN3 pin 35. The setting of clock is shown as Figure 2.3.

2.8D/A Reference Voltage Setting

The D/A converter's reference voltage source can be supplied both internally and external. The external reference voltage comes from connector CN3 pin 31 (ExtRef1) and pin12 (ExtRef2), see section 3.1. The reference source of D/A channel 1 and channel 2 are selected by JP4, respectively. Their possible settings are shown as below:
