Error in MCF548x Reference Manual

I think there's a small error in the MCF548x Reference Manual.

On page 2-2, Figure 2-1. MCF548x Signals, it lists FBCS[5:1] / PFBCS[5:1] (I've underlined instead of overlined)

Beneath it, it has FBCS0 with no overline/active low signal.

It also show's it again on page 2-3

However, on page 2-11 it has the over line for FBCS0

Also again in Section 2.2.1.2 on page 2-16.

Hello,

I double checked what you had mentioned, yes, you are correct. The FBCS0 really an active low signal, so the manual is not consistent. I will let the document team aware this and thanks for your kindly remind.

Hey Fang,

I think I found another error:

Table 2-1 on Page 2-6 (PDF page 50) shows the following assigned to bga pin AE25

However, on Table 2-2, page 2-15 (pdf page 59), it assigns the following:

This again appears on Table 32-1 pg 32-6 (PDF page996)

What is the correct I2C and CAN assignments for that pin?

Thanks you

Zach

Hello, Zach

Yes, you are correct. I am really so sorry for the errors in the manual. The correct pin function for AE25 should be SCL/CANTX0.
