Hi，

Question1:

How to determine SIUL2.MSCR[18] ? Why not SIUL2.MSCR[17] or other num?

Question2:

In the NXP web, How to get mpc5775K pin map?

In the example of MPC5775K-UART_with_Interrupts-S32DS.I see a segment:

SIUL2.MSCR[18].B.SSS = 1; /* Pad PE7: Source signal is LIN0_TXD G17 */

SIUL2.MSCR[18].B.OBE = 1; /* Pad PE7: Output Buffer Enable */

SIUL2.MSCR[18].B.SRC = 3; /* Pad PE7: Maximum slew rate */

SIUL2.MSCR[18].B.PUE = 1; /* Pad PE7: Pull up enable*/

SIUL2.MSCR[18].B.PUS = 1; /* Pad PE7: Pull up*/

/* Configure pad PE6 for LIN0RX */

SIUL2.MSCR[19].B.IBE = 1; /* Pad PE6: Enable pad for input - LIN0_RXD */

SIUL2.IMCR[62].B.SSS = 1; /* LIN0_RXD: connected to pad PE6 */

Sametimes, in the MPC5775K_EVB, I can see LIN0_TXD and LIN0_RXD

Question1:

How to determine SIUL2.MSCR[18] ? Why not SIUL2.MSCR[17] or other num?

Question2:

In the NXP web, How to get mpc5775K pin map?

Hi,

See the device I/O Signal Description and Input Multiplexing tables attached to the device reference Manual as

an Excel file. Locate the paperclip symbol on the left side of the PDF window, and click it. Or open RM and press CTRL+SHIFT+A. Then double-click the Excel file to open it and select the Output Muxing table tab.

Note: this device is still in pre-production status and the Reference Manual is provided only under NDA. If you do not have it, it is necessary to sign NDA in our local sales office: Distributor Network|NXP

BR, Petr
