Original question:

TM4C1294NCPDT: Debugging MCU on custom board

TM4C1294NCPDT: EPI Host Mode Timing Waveform Data

RJ
Intellectual 2550 points

Part Number: TM4C1294NCPDT

Hey Team,

I got a request on TM4C1294 and was wondering if this information is available.

Planning to use the TI TM4C1294NCPDT microcontroller. We are requested timing waveform when using the EPI in host mode, 16 bit unmuxed scheme. He was providing very good support. One pending question is the following: We want to know how many EPI clock cycles it takes for the uDMA to transfer one event from external memory. The data sheet has no waveforms for the uDMA function using the EPI interface.

Regards,

Ramon

    I don't have any timing diagrams other than what is in the datasheet. The use of the uDMA does not impact those timing diagrams. It may impact the time between accesses. Using non-blocking reads and burst reads with the uDMA will optimize the throughput.
