Interfaces to Payload
The MMC has the following interfaces that allow interaction between the on board FPGA and the MMC.
Interface
Description
Payload Reset The MMC controls the Payload RESET# signal. The RESET# signal stays low for app.
200ms after Payload Power is turned on and FPGA is configured.
FUNC_LED2
FUNC_LED2 is an Input to the MMC. A rising or falling edge of FUNC_LED2 triggers the
MMC to flash the USER LED in the front panel (turn off for app. 100ms).
EKEY[4:1]
These signals can be used to transmit connectivity data from the MMC to the FPGA.
This may be necessary in applications that implement different kinds of connections from
the FPGA to the AMC interface.
The implementation in MMC and FPGA has to be done by the customer.
I2C
This I2C Interface can be used by the FPGA to read connectivity data from the MMC.
This may be necessary in applications that implement different kinds of connections from
the FPGA to the AMC interface.
The implementation in MMC and FPGA has to be done by the customer.
RXD0 / TXD0
These signals can be used to implement a serial communication between FPGA and
MMC.
By default, this is used as debug-output of the MMC. Any other implementation in MMC
and FPGA has to be done by the customer.
