Functional Description

JTAG

JTAGEN set carrier board CPLD into the chain for firmware update. In normal mode JTAG is routed directly to Module. Set S3-ENJTAG to OFF to get access to carrier CPLD.

JTAGMODE set module CPLD into the chain for firmware update. In normal mode  JTAG is routed directly to FPGA. Set S3-ENJTAG, S3-M1 and S3-M2 to ON to get access to module CPLD. Attention VADJ is set to 1.8V in this mode.

Power

EN1 is set to logical one after delay.

...

M1M2Description
OFFOFFVADJ: 1.8V
OFFONVADJ: 2.5V
ONOFFVADJ: 3.3V
ONONVADJ: 1.8V, Attention: Also Module CPLD JTAG access is enabled, see JTAG description.

...

Reset

RESIN (negative Reset) to module, can be set by S2 button.

Boot mode

Boot mode is set to SD-Boot, when SD-Card is detected.

RGPIO

RGPIO Master is a 32Bit Remote GPIO Interface to talk with FPGA over 3 lanes.
