Hi,
I have a question about C6742 and C6748.
On customer board, we are using C6742.
But it seem that internal L2 RAM are not enough for the system.
So, we are planning to replace the C6742 to C6748 which has much more internal RAM.
C6742 and C6748 are pin-compatible, so I though we can replace with no hardware change.
But while comparing the C6748 and C6742 datasheet, it seem only USB0_VDDA12 pin configuration need to be changed.
From datasheet, when USB are not used, USB0_VDD12 (N17 pin) of C6748 need to be connect to external capacitor.
In C6742, this N17 pin are "No connect"pin.
If we don't use USB, do I need to connect N17 pin to external capacitor as written in C6748 datasheet page.69 Table 3-32?
By the way, in the following wiki page, it said that when USB0 and USB1 are not used,
USB0_VDDA12 configuration are "No connect".
This is different configuration from C6748 datasheet page.69 Table 3-32.

Which configuration(Table 3-32? Wiki page?) should I follow?
best regards,
