TM4C1290NCPDT: WTIMER question?

Part Number: TM4C1290NCPDT

Hello, 

      Trying to arrange a free running 32 bit timer on this part. The data sheet calls out 8 timers numbered 0-7

on CCS 11.1 the register display only shows timers 0 through 5. Also shows wtimers labeled 0-5. The data sheet for the part does not show wtimer. 

I have the part selected correctly in the projects properties. Not sure why the disparity between data sheet and CCS. 

is the Wtimer registers there to show values for any timers that are combined?

    Hi,

      TM4C129 has eight timer modules (0-7). They are shown in CCS register window. However, 6 and 7 are somehow not displayed after instance 5.  See below. 

     There is NO wide timer for TM4C129.  Don't be confused with the WTTIMER in TM4C123. TM4C123 has 6 16/32-bit timers and another 6 32/64-bit Wide timers.
