Asynchronous Serial Interface
The TVME8300 provides two asynchronous RS232 serial interface ports used with the on board Dual
UART.
Both serial ports are available on DB9 male connectors on the TVME8300 front panel.
2.9 Interrupt
Controller
The TVME8300 uses the MPC8245 Programmable Interrupt Controller (PIC) in the serial mode for all
on board interrupt sources.
The following interrupt sources are available:
