Serial Port 3 Transmit Clock Configuration (J18)
In synchronous serial communications using the MVME761 transition
module, you can configure Serial Port 3 on the MVME2603/2604 to use
the clock signals provided by the TxC signal line. On MVME761-
compatible versions of the base board, header J18 configures port 3 to
either drive or receive TxC. The factory configuration has port 3 set to
receive TxC. J18 remains open on MVME712M-compatible versions.
To complete the configuration of Serial Port 3, you must set J2 on the
MVME761 transition module (Serial Port 3 clock configuration) as well.
