Difference between Muxing_BallMap and Schematic in MPC5775K

Hellow

Now I am confused about which is the correct pin connected to the module.

For example, I made a table to show the difference. Where the MPC57xxMB column represents the pin found in the Schematic of MPC57xxMB（SCH-27237-MPC57XXMB） and Signal Table represents the pin found in MPC577xK_Muxing_BallMap_Rev2_15.xlsx attached in  MPC5775K Reference Manual.

	MPC57XXMB	Signal Table	MSCR	MSCR.SSS	IMCR	IMCR.SSS	Signal Table	MSCR	MSCR.SSS	IMCR	IMCR.SSS
TXD3_SNIMODE	PM5						PG[10]	106	3
TXD2	PM4	PD[4]	52	4			PG[6]	102	3
TXD1	PE12	PD[3]	51	4			PG[4]	100	3
TXD0	PC15	PD[0]	48	4			PG[3]	99	3
TXEN	PC14	PC[15]	47	4			PI[3]	131	4
TXCLK	PK14	PG[11]	107	-	20	1
RXD3_PHYAD4	PK15	PH[5]	117	-
RXD2_PHYAD3	PM1	PH[4]	116	-
RXD1_PHYAD2	PC13	PD[6]	54	-
RXD0_PHYAD1	PC12	PD[5]	53	-
RXDV_MIIMODE	PM0	PD[2]	50	-	91	1	PI[2]	130	-	91	2
RXER_MDIXEN	PM3	PH[8]	120	-
COL_PHYAD0	PM2	PH[6]	118	-
CRS_LEDCFG	PC11	PH[7]	119	-
RXCLK	PC10	PD[1]	49	-	90	1	PH[13]	125	-	90	2
MDC	PC3	PG[9]	105	3
MDIO	PC2	PG[8]	104	3
X1	PA15
ENET_TIMER1		PE[15]	79	3
ENET_TIMER2		PF[0]	80	3
RMII_CLK		PG[11]	107	3
TX_ER		PH[9]	121	4
ENET_TIMER0		PI[1]	129	4

So whats the correct one? If the Schematic one is correct, how could I find the right pin with right MSCR for which module pins have two or more MSCR such as ENET_TXD0, TXD1？

Hi,

Always stick with schematic.

1. Find pin in daughter board schematic (MPC5775K_356BGA_EVB_Schematic_GM.pdf)

2. check appropriate connection on Motherboard schematic (MPC57xx EVB_revC.pdf)

If there are multiple connection for one pin, then there is usually jumper/s to determine the connectivity path.

Sometimes EVB user guide can be useful, however for this particular micro i recommend to stick with schematic.

hi, Peter

Can you give me the follow schematics, and thank you!

Hi,

You can find EVB here:

https://cache.nxp.com/downloads/en/schematics/SCH-27237-MPC57XXMB_RevB.pdf?fsrch=1&sr=1&pageNum=1 

But minimodule schematic is not public so I cannot share it here.

Hi Peter

First, thanks for your reply. There are some more questions about the IMCR register. 

pad_53	pd[5]	w11	53	0	siul	gpio[53]	i/o	General purpose IO 53
				1	dspi0	cs3	o	DSPI 0 chip select 3
				2	etimer0	etc0	i/o	Etimer 0 timer channel 0
				3
				4
				-
				-
				-	enet_macahb	rx_d0	i	ENET receive data D0
				-	flexpwm0	fault[2]	i	FlexPWM 0 fault input 2
				-

How could I configure the enet_macahb_rx_d0 and rx_er .etc. I can't find the corresponding IMCR register unlike rxdv(IMCR90). The IMCR registers only have 93 in MPC577xK_Muxing_BallMap_Rev2_15.xlsx. 

However, in Martin's MPC577xK_ENET_Example:

    /* RX_ER */

    /*

    SIUL2.MSCR[11].B.SSS = 0;

    SIUL2.MSCR[11].B.IBE = 1;

    SIUL2.MSCR[11].B.PUE = 1;

    SIUL2.IMCR[967].B.SSS = 1;

    */

The IMCR number is 967 or as mentioned in 

https://community.nxp.com/message/943047?commentID=943047&et=watches.email.thread#comment-943047 

the number is 967-512=455

But the question is that I do not have the information about IMCR numbers over 93. Where could I find them?
