The description of the CSCRx bit 9 [MUX] on page 11-6 is incorrect.
For both MUX = 0 and MUX = 1 as listed in table 11-5 , it says
0 Non-multiplexed configuration.
which is correct, but
1 Non-multiplexed configuration.
which is wrong ! When MUX = 1, the FlexBus is in multiplexed mode (as borne out by the rest of the description in the table).
