Hello,
I would like to implement External Peripheral Interface (EPI) in Gerneral Purpose Mode to connect my uC with an FPGA. My problem is, that I can not find all the necessary GPIO Pins on my Evaluation Board.
I am refering to table 19-9. EPI General-Purpose Signal Connections, page 1381http://www.ti.com/lit/ug/spruh22g/spruh22g.pdf
There are four modes mentioned:
--- D8, A20
--- D16, A12
--- D24, A4
--- D32
I would like to use the first mode D8, A20, page 1381
(D0): EPI0S0 -> PH3_GPIO51, GPIO Pin 51 is on my evaluation board
(D1): EPI0S1 -> PH2_GPIO50, GPIO Pin 50 is NOT on the evaluation board
(D2): EPI0S2 -> PC4_GPIO68, GPIO Pin 68 is NOT on the evaluation board
(D3): EPI0S3) -> PC5_GPIO69, GPIO Pin 69 is on my evaluation board
(D4): EPI0S4 -> PC6_GPIO70, GPIO Pin 70 is NOT on the evaluation board
(D5): EPI0S5 -> PC7_GPIO71, GPIO Pin 71 is NOT on the evaluation board
(D6): EPI0S6 -> PH0_GPIO48, GPIO Pin 48 is NOT on the evaluation board, TEST PIN 18
(D7): EPI0S7 -> PH1_GPIO49, GPIO Pin 49 is on my evaluation board
The problem is that the EPI Signals are linked to the GPIO Ports and I can´t find all the necessary GPIO Pins on my Hardware evaluation board.
Table 4.1 GPIO Pins and Alternate Function, page 338 http://www.ti.com/lit/ug/spruh22g/spruh22g.pdf
MY QUESTION: How can I use the EPI Inteface if I can´t find the necessary GPIO Pins on the Hardware.

Is there any opportunity to use other EPI Signals for my Data and therefore other GPIO Pins.
