No current limiting or overvoltage protection components are included on the GPIO signals of the GR716-BOARD board. The signals are connected directly from the microcontroller to the expansion connector. Care must therefore be taken to ensure that any external circuitry connected does not exceed the allowable voltage limits for the input/output pins. -
Page 15: Debug Support Unit Interfaces
Program download and debugging to the processor is performed using the GRMON Debug Monitor tool from Frontgrade Gaisler ([RD4]). The GR716 microcontroller provides a UART based DSU interface for Debug and control of the processor by means of a host terminal, as represented in Figure 4-9. -
Page 16: Oscillators And Clock Inputs
GR716-BOARD Oscillators and Clock Inputs The oscillator and clock scheme for the GR716-BOARD Board is shown in Figure 4-11. Two oscillator inputs are required: CLK for the main system clock, and SPW_CLK for the SpaceWire clock of the microcontroller To allow the GR716 Microcontroller to operate in a stand alone manner a crystal is required on the board which is connected to the Crystal oscillator interface for the GR716. -

To perform program download and software debugging on the hardware it is necessary to use the Frontgrade Gaisler GRMON3 debugging software, installed on a host PC (as represented in Figure 4-9). Please refer to the GRMON3 documentation for the installation of the software on the host PC (Linux or Windows), and for the installation of the associated hardware dongle. -
