Configuration and Installation
The configuration for jumper W5 specifies whether a board is to drive the onboard 10-MHz
oscillator onto the RTSI bus, receive the RTSI bus clock, or disconnect from the RTSI bus clock.
This clock source, whether local or RTSI signal, is then divided by 10 and used as the Am9513A
frequency source.
The jumper selections are listed in Table 2-9.
