MOD54415 Signal Availability
Posted: Wed Feb 06, 2013 5:12 pm
I'm getting ready to start a new design with the MOD54415 and have some questions on availability of some of the signals.
I want to make use of pretty much ALL of the UART's so my concern is making sure I'm not going to have any conflict with those pins.
1: If I'm using the integrated Flash Card support on the core module will that interfere with any of the signals that are brought out on the header? (Specifically the NFC_ signals).
2: Does the integrated Flash Card support require the SPI lines or is that only for external flash card support? I currently use the SPI pins for Wireless module.
3: I do need to be able to use an external clock for UART baud rate generation. From the data sheet I see: "Each UART can be clocked from an internal or external source. For external clocks, each UARTn can be clocked by the corresponding DTn_IN vnput pin." However, I don't see those pins listed in the tables anywhere?
