How many chip-selects does the MCF5445x have (6 or 4)?

[M_H_]

According to 19.1.1 in the MCF54455 Reference Manual (Rev 2) the part has 6 chip selects (FB_CS[5:0]) and it provides details on the six chip-select address registers and six chip-select mask registers in 19.3.1 and 19.3.2 respectively. However, I can't find pin numbers for FB_CS4 and FB_CS5. 

In the MCF5445x Microprocessor Data Sheet I can only find reference to FB_CS[3:0] so does it in fact only have 4 chip-selects or are FB_CS4 and FB_CS5 multiplexed with some other pins?

Hi,

  The MCF5445x FlexBus has 4 chip selects.  Looks like the FlexBus module has up to 6, however only 4 where implemented on this device.  Unfortunately some references to the 6 slipped into the reference manual.   I've submitted a ticket to fix those errors in the next revision of the manual.  Thank you very much for your feedback.
