Functional Description

JTAG

Set JTAGENB(J3-136) high to get access to CPLD via JTAG, otherwise CPLD JTAG Pins can be used as GPIO.

Power

EN_1V is set to constant high.

Boot Mode

CPLD_GPIO3 (J2-16) is used to set boot Mode Pin BM2_MIO4. Signal is inverted to be compatible with second XMOD on TEBT0782

J2-16Description
lowSD Boot*
highQSPI (default)

* not supported with TEBT0782

Reset

nRST_IN drive POR_B as open drain.

U27(TPS3106) or nRST_IN can reset Zynq.

UART

MIO14 is connected to CONFIGX.

IO Expender

Currently not implemented.

BOOTMODE is connected to MIO15.

RGPIO (beta)

RGPIO Master is a 32Bit Remote GPIO Interface to talk with FPGA over 3 lanes. System need RGPIO IP on FPGA side.

  • RGPIO CLK is  FPGA_CPLD1 (up to 50MHz).
  • Output is FPGA_CPLD2
  • Input is FPGA_CPLD3
RGPIO from FPGADescription
0...19Connected to EXT_IO(even numbers), if RGPIO is activated, otherwise EXTIO is high impedance
20...23Connected to RGPIO 20...23, if RGPIO is activated.
