2.4.4 J7 Terminal Interface
The VMP3 provides one serial interface for supporting a terminal port (TERM1). This interface
is realized using one of the MPC8541E on-chip UARTs, and as such provides only a two wire
interface without hardware handshake signals.
The connector J7 provides interfacing to the TERM1 port. This port can also be used as a low
speed solution for firmware updating. The signal levels on this connector are RS232 compliant.
The UART itself is a 16550 type UART.
The following figure and table provide pinout and signal information for the TERM1 interface.
