About Timer64 and its registers on C6657

Hello everybody!

I have a question about C6657's timer registers, I saw in the datasheet (TIMER64P) that there are 13 registers but when I debug my program for testing timers (on CCSv5) I just see 8 registers ( EMUMGT_CLKSPD, CNTLO, CNTHI, PRDLO, PRDHI, TCR, TGCR, WDTCR ) and I'd like to know whether or not on this DSP exists the missing registers  (RELLO, RELHI, CAPLO, CAPHI, INTCTLSTAT).

Thanks in advance!

Greetings

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). Please read all the links below my signature.

    We will get back to you on the above query shortly. Thank you for your patience.

    Note: We strongly recommend you to create new e2e thread for your queries instead of following up on an old/closed e2e thread, new threads gets more attention than old threads and can provide link of old threads or information on the new post for clarity and faster response.

    Dear Fernando,
    No, DSP has those registers physically but it might not exported to CCS IDE.
    I too checked with latest CCS IDE version (CCSv6), still doesn't exist.
    You can access those registers (RELLO, RELHI, CAPLO, CAPHI, INTCTLSTAT) using direct MMR address via CCS memory window.
