GR-UT699 Development Board

User Manual

2.6 Serial Interface

The

UT699RH

ASIC, provides a single Serial port, with TXD/RXD pins, and the

GR-UT699

board provides an RS232 driver/receiver chip and routes these signals to a front panel
connector.
The front panel connector type for the UART interface is Female D-Sub 9 pin type with a
standard pin-out for serial links.

2.7 Debug Support Unit (DSU) Serial Interface

The

GR-UT699

unit provides a interface for Debug and control of the processor by means of

a host terminal via the DSU serial link to the

UT699

ASIC, as represented in Figure 2-8.

The board provides two possibilities for connecting to the processor's DSU interface:

1. USB MiniAB connector with USB to Serial interface chip
2. JTAG DSU interface

The baud rate of the serial link is specified by the host computer, and the DSU interface in
the

UT699

ASIC auto-detects and adjusts its baud rate to suit.

The

DSUENable

signal input to the processor is connected to a jumper on the PCB. In
